Before you all decide to move to California's Death Valley.....
I drove to the Nats again this year. As I crossed the coastal valleys the temps were in the '90's. Traffic was heavy as I crossed the Los Angeles basin but it completely stopped when I got on the I-15 as I approached the Cajon Pass. Took about 45 minutes to move a couple of miles. I couldn't believe the cause: CalTrans had the interstate closed down to one lane northbound while--believe it or not--they moved their snowplow trucks around in the other lanes! I crossed over the first mountain range, and saw the last of the snowfields high above on top of Mt. San Antonio (Mt. Baldy to the locals) on the north face and melting fast after a record snowfall winter. (ie. it wasn't a continuation of the drought!) In the high desert, the temps started at 112F and moved up from there. Thru famously hot places like Barstow, Dagget(!), and Needles. People from Death Valley go to Dagget to cool off! I kept a close watch on the truck's tranny temp gage, in addition to the engine temp gauge, which I figured would hold at just below 212 until everything suddenly boils over with no warning....
It started cooling off in Arizona once well east of Lake Havasu, down into the single hundies (less than 110), and continued to cool thru New Mexico and the Texas panhandle which reached about 102 to 105 in the middle of the afternoon. Same for Oklahoma. Then it dropped a little more crossing into Missouri, but remained right at the Century mark all the way to Muncie.
Since the back of the truck does not benefit from air conditioning, ya gotta be careful what/how you pack. I always forget that the lids to the epoxy will pop off from the altitude changes and heat, and at least one of the bottles/tubes will overflow. I have learned to pack that stuff separately in Ziplock bags so it is at least easier to clean up. And I stopped packing the diesel fuel in the back because it loses ether right thru the metal can in those temps. It goes in the cab from now on.
Funny, standing on the asphalt at Muncie all week didn't seem too bad. But CL racing means running---so run we did!
Still and all, if you wanted to take a few days in Death Valley for your health, I bet there is plenty of room. Just be sure to bring a tent because they ain't got no shade trees!
