Tesla Model S - Road Trip to Yosemite with Boy Scouts
All-electric road trip
from Orange County to Yosemite

My son is a Boy Scout in a Troop which frequently camps out. On at least a few of these campouts per year, the Troop visits a famous location, and this year it is Yosemite National Park. I've visited Yosemite since I was a child, but never have I tent-camped anywhere near there, so I was definitely on board with providing adult support for this Boy Scout campout.

With over 10,767 miles of electrically-powered road trips, I knew my all-electric car gave me the freedom to execute this trip plus the choice to do so in a way that was more consistent with Boy Scout principles than using any internal-combustion vehicle.

While we appreciate the planning by Troop leadership, the selection of the campground 32 miles west of Yosemite Valley was made without consideration for electric cars and assuming only internal-combustion cars were travelling, so I was completely on my own for determining charging. The real problem is not one of vehicle range (because the gas cars on this trip had to refuel near the campsite too) nor was it even a problem of infrastructure because the property hosting the camp had dozens of NEMA 14-50 compatible outlets (exactly what I use at home) and therefore know how to install and maintain them; instead it is a problem of management and policy by the owner of the grounds. RV parks in Vernal and Bryce, Utah, are more enlightened than this Northern California proprietor. No 50 Amp Service for You
This 50 Amp charging is for Thousand Trails Members only, no exceptions, not even if I paid. Management did not allow me to enter the area nor ask someone staying there, nor at the other cabins with 50 Amp outlets outside the Member area, if I could use a 50 Amp outlet they were not using.

By contrast, the preferred scenario is to charge overnight while on a multi-day road trip, exemplified by the those owners who participate in the Tesla Destination Network. Rather than argue with the management, one should simply stay some place with a modern policy or near other Level 2 charging. But no the location of this Troop's campout was set, so I could not rely on charging near the place where I slept.

Nonetheless there was and is a way. Heeding the Boy Scout motto "BE PREPARED", I duly and thoroughly prepared, even when no other adult on the trip had any idea how I was going to pull this off. They didn't know I could rely upon the robust and well-developed deployment of the Tesla Supercharger Network, which gave me a way to obtain all the charge I needed despite where the Troop booked.

I also purchased a NPS Annual Pass, like I did in our family's 4647-mile road trip. Read on for our picture log of our Boy Scout trip in my Model S.

Cargo Space
The cargo space in the Model S was plenty for this trip. The front trunk held my duffle bag holding all my clothes and gear plus extra shoes. The back trunk carries two Scouts' duffle bags, two large tents, sleeping bags, sleeping pads, jackets, portable chairs, helmets (for rock scrambling), cooking gear, video camera, four first-aid kits, extra water, extra charging cables, hiking boots, and provisions. I also fit in my violin and music stand. frunk   trunk

Also, my S was one of the two pilot vehicles that left a day earlier than the official Troop departure date. I wanted to do this so that we could leave at a comfortable time of day rather than some ungodly hour. In addition doing so was Helpful to the Troop because the campsites were first-come-first-serve, so I was assigned, as the first to arrive, to strategically choose the first two campsites so that we can grab two more nearby the next morning in preparation for the arrival of the entire Troop, over two dozen in all, on Friday. My passengers were my son and another Scout; our families have known each other since Wolf Rank of Cub Scouts so we have all the proper permissions; geez, don't even go there...

We left from my home after loading up the car. Traffic in LA was significant, so the navigation routed us via the 605 to 210 route to bypass downtown and Santa Monica. The arrival at Tejon Ranch was a welcomed by all to take a bathroom break at the Petro Wheeler Ridge. I have not been at this Supercharger since 2013. There we shopped for a few provisions but couldn't find the right charging cable (he left it at home) for the other Scout's electronic gear.

Fresno Tesla Supercharger

With the traffic behind us, the next leg of driving was very pleasant. As planned we had lunch in Fresno, and here we chose the Five Guys for a comfortable, filling, and enjoyable lunch. As before a bathroom break was required before we could even order.

Cost to Charge: $0

Before we go on I should point out how the navigation in my new 100D Tesla, with a maximum of 335 miles of EPA-rated range, was about to route us. Since the last time I drove all-electric this way, the number of Supercharger sites are numerous and easily more than enough for our purpose. When I first plotted a course to Yosemite Lakes RV Resort, the navigation enthusiastically plotted a route with only one charging stop in Kettleman City on the I-5, and each of the two legs of travel would be a little over 3 hours.

I was very proud to know that the technology has now reached the point where I can drive that route with solely one charging stop. It also makes me proud of the technology to know that the bottleneck instead was human physiology: I would be pushed to my limit to drive for 3+ hours straight without a bathroom break, but more importantly both boys with me cannot possibly ride non-stop much beyond 2 hours.

Therefore I manipulated the navigation as we traveled to force it to route using Supercharger stops at roughly two-hour intervals (the interval Tesla wisely spaces their Supercharger sites) for the itinerary to be human-compatible. The side effect was that the car collected way beyond enough charge as we travelled.

Bathroom Anxiety

I also bought a chocolate milkshake at Five Guys as a dessert I could enjoy on the road. Once we were comfortable we returned to the car to unplug, but one of the boys wanted to get that new charging cable, so we drove to the Target on the other side of the parking lot to shop. That took an extra 20 minutes right there, but remember, for safety's sake and other good reasons, this is not and should not be a race.

Tesla in Coulterville
On the way north we encountered some significant road construction along highway 49 requiring a wait for oncoming traffic to pass before we were guided through the available single lane, so that was a delay.

One of the small towns on the route was Coulterville, a town my in-laws used to live many years ago. It so happened that the boys really really needed to use the restroom at this time, so we found one at the town's swimming pool.

This reminded me of a phenomenon I named Bathroom Anxiety on our 4647-mile road trip last year. The boys digesting lunch must have triggered this immediate need. It was not that much further to the campsite, but I felt it was wise to heed their call of nature.

We drove to the front desk and found a significant line of other guests, mostly RV drivers but a few campers. Due to understaffing, it was another 30 minutes before we could check in.

Once we obtained all the paperwork and instructions from the staff, we quickly got back in the car, drove, then scouted for the best campsites on the property and tagged them as instructed.

With that in place we unloaded our gear and set up camp and spread out in such a way it would be obvious for the other pilot vehicle expected to arrive a couple hours later. There was no cell-phone coverage here so I could not message nor call them from here.

We did not have any of the cooking equipment because the Troop was bringing that tomorrow, so we drove to Groveland for dinner 19 miles to the west. It so happens that is our closest Supercharger. The boys and I had a great dinner at Hotel Charlotte.

As we were finishing dinner my Tesla app was reminding me I should unplug lest my S sit there idle. The car was finished filling up before we were. After paying the bill, we drove to the MarVal, the local grocery store, to pick up a few fun provisions like snack foods and Oreo cookies before driving back to camp to meet with the others arriving tonight and decide on the remaining campgrounds for the Troop.

Preparing for the Arrival of the Troop
Friday, June 28, 2019

Mine was the blue tent in the picture. I placed it near the river, and the sound of its rushing white spray was surprisingly soothing. This, and every night here, despite temperatures in the 40s, I slept very well, and definitely the best sleep at camp I have ever had.

Intentionally, we all slept in late Friday morning. We drove to a late breakfast at Tangled Hearts about 11 miles away. When we returned we enjoyed the wide variety of facilities that this RV Resort had to offer such as mini golf, horseshoe throwing, foosball, billiards, and the WiFi in the lodge. These were all things the Troop was not to be told about once they arrived.

Tesla at Campground

Later that day I took out my violin to play old classics like Off to California, Whiskey before Breakfast, Faded Love, and Ashoken Farewell with the rustle of a breeze flowing through the trees in the background. It was very pleasant, and our neighbors later complimented my performance.

Late in the afternoon the Troop arrived to set up camp for real. I cannot post detailed pictures of them per BSA rules.

Yosemite National Park
Saturday, June 29, 2019

Now that we were in full Boy Scout mode, the Troop prepared breakfast and packed lunch for a day excursion into Yosemite. Bear in mind that Yosemite Valley is still 32 miles away from our campsite, so the vehicles were definitely part of the plan. I allocated two 64-mile round trips of driving starting today, and, just in case I couldn't get any charge at this RV Resort, allowed time Sunday night to top off back at the Groveland Supercharger.

Another father and his two boys joined my son and I in my S. This was their first time visiting Yosemite. Although they have a neighbor with a Model S, this is was also their first time in a long drive in an electric car. We thoroughly enjoyed it. I even tried the Autopilot on these windy roads, and it behaved admirably, much improved from my tests in January. The speed limit was usually no more than 35 mph to protect the bears from being killed by speeding cars.

Unlike some of the Troop, that father and I were happy to jump into the photo opportunities such as the Yosemite sign as we went. It was easy to catch back up with the Troop later. The road took us down into the bottom of Yosemite valley, and I identified many landmarks like El Capitan and Bridalveil Falls for them. The Troop leadership said our first stop was to be Glacier Point, which is a substantial 25-mile drive up from the valley floor after driving 30 miles, for a 1.5-mile hike to Sentinel Dome.

Yosemite Panoramic

Parking at Glacier Point was extremely crowded, but we all found each other for the hike up. This hike on the other hand was gorgeous and, to me anyway, quite moderate and rewarding. It was covered in forest until we neared the exposed granite. The view from the Sentinel Dome was stunning, allowing 180° vistas simultaneously viewing famous sights El Capitan, Upper and Lower Yosemite Falls, and Half Dome. A short walk to the east side of Sentinel Dome allowed a view of Half Dome, Vernal Falls, and Nevada Falls.

Although exposed to the sun, this was an appropriate time for lunch before heading down. However this hike was a test for many of these boys and about three-quarters of them thought it was too hard. I loved the hike and the views and the great photography. Despite my visiting Yosemite a dozen times, this was my first time at Sentinel Dome.

It wasn't long before we were back down at Glacier Point, a must-see vantage point, to see additional spectacular views of Yosemite, including the valley floor 3200 feet down.

The Troop leadership decided we should go to Mariposa Grove near the south entrance to Yosemite. It is a less well-known region filled with Giant Sequoias. I also didn't know it was additional 33 miles of driving, again with 35 mph limits.

The walk amongst these enormous trees was flat and pleasant. They seem much like the forests in Sequoia National Park I've visited a few times.

Our return to camp was another 55 miles of driving. The other father and I enthusiastically took a stop at the famous tunnel view (top and bottom of page) to shoot pictures. However at this point all this driving got to many of the boys. My son and I of course had all of Friday to relax at camp, but the other boys just had 7+ hours of driving the day before to be hit today with 143 miles of driving in 35 mph speed limits; that's over 4 hours of driving on their first day in Yosemite. Once I knew we drove that long I felt sorry for the boys because that's a lot of driving around. 143 miles also blows right through the mileage I budgeted for two days.

Just before entering the RV Resort, all the other drivers immediately stopped at the gas station at the highway 120 entrance to the RV Resort, so clearly they all felt their range tested too. I ate dinner at camp first before driving to the Groveland Supercharger one evening earlier than planned. I had a nice cheesecake at the Iron Door Saloon, the oldest continuously operating saloon in California, and caught up on some work with my laptop via local WiFi while it charged. Still it was clear that shifting my one top-off to tonight instead of tomorrow was all my S needed.

I returned to camp with 295 miles of range. I already knew that I only needed 120 miles of range to reach the Fresno Supercharger from camp and expected to drive about 64 miles before then, so I knew I would be fine with range.

Mist Trail, Vernal Falls, and Nevada Falls Sunday, June 30, 2019

Today our plan was to split into two groups: about a dozen boys would go with a handful of adults to climb rocks on a short valley hike while five boys and five adults would hike to Vernal and Nevada Falls: Not much driving in any case.

Before we were about to leave, the Assistant Scoutmaster took me aside advising that I leave my car at camp. Why? Because he thought I was using up too much range so I wouldn't be able to drive home.

This was interesting because it seemed like the gas-car driver was having range anxiety on my behalf, whereas I was experiencing none. I quickly told him that I topped off at the Groveland Supercharger last night, so now my S is in the upper 200s of range. Reassured, he agreed to my taking another drive.

I took the same father but two other boys. His sons and my son went to the rock scrambling. Since I hiked to Vernal Falls when I was in seventh grade, to Nevada Falls in high school, and to Half Dome in 2003, only the 18-year-old who completed his Eagle Scout rank last year has as much experience on this trail as I by hiking Half Dome last year. He and I were automatically the guides.

Because of all the extra snow pack from last winter, the waterfalls were amazing. The Mist Trail was more like a rainforest, drenching all of us despite bringing ponchos, yet surrounding us with bright rainbows.

Past Vernal Falls the weather warmed up. We had lunch at the top of Nevada Falls and the sites were awesome. We hiked down the John Muir trail much like the return from Half Dome my group did in 2003.

The only thing not so fun was the heavy traffic through Yosemite on the way back. It felt like the Glacier Point parking lot. While driving on Autopilot, I opened my window and stuck my iPhone out backwards to shoot Half Dome.

Tesla driving in Yosemite traffic

After some back and forth with the management about 50 Amp charging Friday, they did offer to let me use 120V charging at an RV parking spot that barely is used anyway because it is too short for most RVs. I thought it would be better if I simply accepted the offer rather than come off as snooty and reject the 120V, so I moved the car to the short RV spot and plugged in. It was only 3 miles of range per hour. I knew I already had more than enough to get to Fresno, but I could tell myself that my margin of error was even greater this way.

Monday, July 1, 2019

Everyone knew they wanted to head home and try to get out as early as possible, but such things don't always go to plan. I helped make pancakes as part of a larger breakfast. Then we cleaned up and packed up our tents and other gear. It took a little while to figure out the balance of gear between vehicles. When it was finally done the Troop circled up and moved out.

Tesla Breaking Down Camp

The navigation again took us through Coulterville, but today we had a little more flexibility for some excursions. I had not been to the Lazy J Ranch where my in-laws lived for a decade since the time they sold the place several years ago. I was curious to see if anything changed and wanted to take pictures to share with that side of the family. So I disobeyed navigation to take the Granite Springs road and drive there from several-year-old memory. Quickly we found the place, so I parked and took pictures.

Over lunch we discussed where we wanted to go next. We had a choice for our next stop: Tejon Ranch again or Kettleman City, a Supercharger where we've never been before. So we chose to cross from the CA-99 to I-5 to sightsee at Kettleman City.

This Supercharger site is the first to have an actual "Tesla Lounge" where people could relax, shop, have coffee, play games, and enjoy a comfortable air-conditioned rest stop with WiFi. The key-code to get in the Tesla Lounge is visible only in the navigation. This site also has 40 stalls (the largest in America!) to make it a major transportation hub for Tesla drivers between northern and southern California. We saw families taking their kids to the children's games or bringing in lunch. We saw business travelers using the cubicles to charge and use their laptops.

We took a comfortable bathroom break and explored everything the lounge had to offer. I bought a Kettleman City Supercharger t-shirt and two Tesla-styled cellphone chargers for the boys with me. The charge here was really unnecessary to accomplish the trip. We spent 28 minutes here.

From Kettleman, the navigation told us we could make the last leg of the trip on the remaining charge. However, after two hours it was completely clear we needed to use the restroom.

All the routes home had really bad traffic. The navigation surprisingly guided us through downtown LA, but I had to concede that the other routes would just be longer. We were only 20 minutes behind the gas car group, completely explained by our sightseeing in Granite Springs and Kettleman City.


In our Boy Scout Troop the Scouts recite the Outdoor Code, an embodiment of Scouting principles, as part of the opening of every Troop meeting. The last line of the Outdoor Code reads:

Be conservation-minded.

MeritBadge explains that line means:

I will learn about and practice good conservation of soil, waters, forests, minerals, grasslands, wildlife, and energy.
I will urge others to do the same.

Many including the Union of Concerned Scientists have conducted thorough research that show that using an electric-car, even using electricity from the US grid but especially California's grid, for a purpose causes less harm to the environment than a purely internal-combustion engine (ICE) car for that same purpose. It is even easier to prove that powering the electric car is more conservative with resources than any ICE-powered car by a factor of 3 because all ICE-powered cars are inherently about far less efficient, limited by the Carnot cycle to at most 25% efficient. If you want to conserve resources, then use that fossil fuel in a stationary power plant with combined cycle and send that energy over the grid to the electric car and each gallon of gas could power the electric car 3 times as many miles as burning it in an ICE-powered car. Conversely using an electric car uses 3 times fewer resources to "fuel" the trip as a non-hybrid ICE-powered car. The ratio gets even better as more renewables power the grid, which is common on the US west coast.

Therefore it is inescapable that every Scouting event plan in America should encourage if not require such trips, especially ones of great distances like this, to be powered using all-electric cars rather than ICE-powered cars. Anything less goes against the principles of Scouting. The electric car should be the standard, and by all rights an explanation why the ICE-powered car was allowed should be demanded.

All the vehicles on this Troop outing, except my Model S, were non-hybrid ICE-powered vehicles.

Do I urge, as the Outdoor Code implies, the other adults of our Boy Scout Troop to each buy a long-distance all-electric vehicle like mine? That is my dilemma; perhaps I should save it for another day.

However it does make me think that I should coordinate with our Outdoor Chair to make sure for future long-distance campouts: 1. overnight Level 2 charging is near the campsite if we're driving a lot (200+ miles in this trip) while camping; and 2. an all-electric caravan is allowed to drive separately from the gas-powered caravan. My results on this Troop outing was a proof-of-principle that all of the above is possible.

I speak for the trees. I speak for the trees, for the trees have no tongues.

But clearly most people do not know the above, nor do they know they do not know. Most seem astonished anyone would drive to Yosemite entirely on electricity. Others have yet to realize: Electric-car owners like me are not an aberration; we are inevitably a growing part of the community, and there is no turning back. For example that 18-year-old who recently completed his Eagle Scout proudly identifies with the speaker of the quote "I speak for the trees".

Driving Electric

Like before, the Model S makes a great road trip car. Traveling without the extra engine and transmission noise, creating an low-frequency rumble and roar that shakes one's innards, makes for a confident and relaxing driving experience. Not only were the two Scouts in my S happy on these two longest driving days: their behavior was beyond reproach.

As the other father agreed, this S was especially enjoyable inside the National Park. We rolled down the windows to enjoy the beautiful scenery and listen to the trees as our vehicle makes zero noise. Only the gas cars around us disturbed the paradise. I never want to use a gas car again to visit a National Park.

Tesla's technology came through for us humans. As before, humans were the limitation, not Tesla technology. The realities of human physiology were expressed both by the poor boys suffering from the instances of Bathroom Anxiety and the unexpected 143 miles of driving on Saturday that my S had no problem executing.

Members of our Troop would never exhibit the reckless attitude about non-stop road trips I see elsewhere because such an attitude is against BSA policy:

"Driving time must be interrupted by frequent rest, food, and/or recreation stops. The intention is to include sleep and thorough rest breaks while traveling long distances. Don't drive while drowsy. Stop for rest and stretch breaks as needed. Fatigue is a major cause of highway accident fatalities."

Rushing from place to place without delay, as some critics presume, is not a lifestyle we should expect; in fact it is unsafe. Maybe uncommitted single people and truck drivers can live that way, but the pace of a group with children works best at a considerably slower pace. It so happens that Tesla designed its cars and Supercharger network to fit that real-world human pace very well.

This was also the first time I used Autopilot on a long road trip. I was pining for this capability on my 4647-mile road trip last summer, and it delivered. Autopilot was excellent at handling the little details of staying in the lane and following at healthy distances, allowing me to conserve my human energy to be more alert to my surroundings longer and make better high-level decisions about the trip during travel. The biggest "problem" was the impatience of the other drivers, thinking it odd that my car was changing lanes slower than sports-car drivers out here would when in fact Autopilot was simply programmed to be careful. It even handled Yosemite's curvy roads impressively well.

Thanks to Tesla the cost to refuel on this 1092-mile trip was $0! That's a conservative budget alright.

With this trip I have 11,859 miles of all-electric road trips under my belt. I should have received my EV Road Trippin' Chip, if there was such a thing, by now.
