Somewhere I missed a day or something, since this is actually day 14, not 13? Anyways, left the salt flats (see picture, at start still has vegetation, later there is just nothing but white) this morning. Its been a cold day, and the white of the salt almost looked like snow at first... That would come later. Really flat and really straight crossing. If your speed delta from other cars is only like a few mph it takes like 10 minutes to catch up to the next car to pass. Also, warning: the gas stations are spaced out, there isn't one for about a 70 mile stretch.
Crossed over my first set of mountain ranges at salt lake city, up to around 7000 ft, snow either side of the highway again. Then you're in wyoming. It's kinda meh, its not quite boring, but close. There are lots of hills and stuff but its fairly unpopulated and only gentle curves. Miles go pretty quickly. There isn't really anything to look at except lots and lots of snow fences. Also, it seems like every 5 miles there is a sign saying "strong winds next 5 miles"... How about at the start they just put up a sign, "strong winds next ALL of wyoming." Fortunately it was a tail wind, so didn't really come into play. Crossing the second major range at laramie takes you up to 8500ft, glad I had enough gear to keep warm. I am just into nebraska, and will cross it tomorrow.
