I’ve had the pleasure of throwing iron a couple of times this winter so far, to get over Soldier Summit on US 6 SE of Provo, Utah to get to or from Albuquerque.I have friends out in Colorado and they keep chains in their pickups but it is different country out there. I believe some mountain passes still require chains on semis and require 4x4 or snow tires.
I don’t have any pictures of proof. Usually too busy trying not to get hit by some idiot. But here’s a picture to give you an idea of the terrain, as well as the task at hand.
