Well, we waited a little too long. I hear October can be pretty wintery in the mountains especially. We are thinking the best route is through Billings, Montana and then N. We have a 4-wheel drive pickup but one stretch has me worried. My concern is the 968.7 mile stretch from Provincial Route 2N to W/Provincial Route 1 (through the mountains). I can't figure out if there are any gas stations etc. anywhere.Has anyone out there ever done this drive? Any recommendations would really be appreciated!
