I am planning a solo drive from Edmonton to just north of SLC between Christmas and New Years using the Coutts border crossing. I was wondering if anyone has done this drive, especially in the winter around Christmas, how long it should take, how long I can expect to be at the border, and if I can realistically do it in one day? Do i need chains? I've mapped it out and while Great Falls doesn't seem far enough to stop if I have to, by the time I get to Idaho Falls I may as well drive the extra 2 hours! Any info would help. Thanks!!!!
