|9:04 am||Departed Las Vegas||232|
|9:51 am||Arrived Primm Supercharger||178|
Eager to return home ahead of schedule for our crossing of the Mojave Desert,
our family decided to depart Las Vegas as
early as we reasonably could.
Nevertheless we needed a bathroom break at the McDonald's in Primm.
Cost to Charge: $0
Range/Distance ratio: 1.29
|10:07 pm||Departed Primm||215|
|11:43 pm||Arrived Barstow Supercharger||61|
Conditions: Fast, 100°F
Per the schedule, this leg was two hours.
Leaving Las Vegas at 9 am and some fast driving made it possible
to start lunch at the Chili's in Barstow before noon.
Cost to Charge: $0
This was the last stop I planned on my itinerary before we arrive home.
While we were eating lunch, I wanted to check traffic conditions on my phone
to get a new estimate for our arrival time.
I didn't know why my AT&T data connection was failing and couldn't give me an answer,
so I just wrote it off as another AT&T coverage problem.
My previous calculations would have us arrive home a little over two hours later.
|Blue Cut Fire blocking Cajon Pass
After our 9 am Las Vegas departure, and therefore unknown to us,
the Blue Cut Fire
started at 10:30 am. This wildfire grew to 6500 acres by the end of the day after blocking
I-15 at Cajon Pass, precisely on our route south of Barstow.
Shortly after we departed Barstow, the smoke from this fire was readily apparent.
We finally were able to obtain news about the event.
This was no joke.
Little did we know days later the fire would expand to over 37,000 acres.
It was a major real-world emergency prompting fire crews from all around to respond and
mandatory evacuations of ultimately 82,000 residents.
No one could predict this so how could it possibly be on our travel itinerary?
The fire blocked our direct route home.
No wonder my Tesla navigation was not routing us through Cajon Pass.
Speaking of driving the car, did we panic?
Did we worry about this electric car running out of range?
No of course not.
In fact the Tesla navigation was offering detours.
At first it routed us to highway 14 via Palmdale, to join up with I-5 and I-405.
That was a long journey, bringing us home very late.
I knew that part of Los Angeles has four Supercharger sites, so again we would not run of range.
Then it offered a route through Hesperia, by Silverwood Lake, and over Crestline.
This route I knew because we took
the reverse two months ago to Vegas.
Meanwhile we could see white ash from the fire falling on the car.
Near Silverwood Lake we could see four fire helicopters picking up water from the lake to bring
it to the fire, plus two fire airplanes dropping red-dye fire retardant just past the ridge line.
Not that this was a great route.
Remember that thousands of other drivers are looking for a way around Cajon Pass too.
The northbound traffic was enormous,
so local sheriffs were outside in the heat directing traffic through
the major intersections of Crestline and other highways.
Meanwhile we pointed out to the kids the emergency aircraft trying to put out flames,
and when they asked why it was so slow we said, "it's the fire",
whose orange smoke was pervasively apparent.
We set the air conditioner on recirc.
|Rancho Cucamonga Supercharger
Range/Distance ratio: 1.92 (!)
|12:41 pm||Departed Barstow||233|
|4:28 pm||Arrived Rancho Cucamonga Supercharger||116|
Conditions: 6500-acre fire, First-responder vehicles, Major highway closures, Emergency detour, 105°F
Cost to Charge: $0
After three and a half hours of driving, we made the decision we had to stop at Rancho Cucamonga for a
To reward the kids for their good behavior, we bought them Ben & Jerry's ice cream.
Us grownups could use a break too.
The car navigation said that we had enough range to make it home without recharging,
and anyone can see its prediction confirmed by reading ahead.
Human physiology and a regional disaster together made us take an unscheduled stop, not the need to charge.
So even when something big goes wrong, Tesla's technology works.
(Ironically we made an unscheduled stop here
at the beginning of the trip, also to go to the bathroom.)
Range/Distance ratio: 1.07
|5:12 pm||Departed Rancho Cucamonga||233|
|6:24 pm||Arrived Home||173|
Conditions: Traffic, 103°F
Driving at rush hour was not the plan, but circumstances made it so.
The fire today made it a relief to be home.
