I'm riding to Montana on May 30 to visit relatives on their ranch. I have a route picked out for the way there. If you have been in the area and want to make suggestions, go for it. The only thing that is for sure for this trip is: I want to take the HWY 20 to Winthrop, as well as stay off major highways. Glacier National Park looks inviting, but I hear traffic can be terrible (I'm not sure when tourist season starts though, I might be going through before the campers come out). Tips encouraged.
