I'm not 100% sure of the exact location where I was on the highway as I was driving at the time and I wasn't paying attention to the towns as I was driving all the way to LA. What I do know is that it was a fairly rural area and that I was headed south on the I-15 well past Victorville but wasn't all the way down to the 210 yet.
