OLASHY: please don't worry too much about any of this bad weather talk - in earlier post or this one to come. If you do encounter any bad weather, just wait it out and you'll soon be fine, they keep the roads clear most of the time in the US.

GLC: sorry I assumed those chain lights were for everyone. And this drive happened on the morning after a 6inch+ snowfall overnight, and the snow, fog and wind still swirling around when we set off for the mountains. We also received warnings about driving across the mountains the night before from three (3!) different local people. The gist of it was: 'don't travel tomorrow, if you can possibly avoid it', and 'people die up on those mountains, boys'... (We stocked up on water and dried/cured meats, just in case..)

But as it turned out, this day was one of the greatest Road Trip days I've ever encountered, going through all that snow and all the way to the desert of Utah in one day!

P.s. You should invest in one of those small and cheap 'dashboard cams' for your trip. The driving videos you'll capture will be amazing.
