I'm part of a group that is leaving Dallas on August 31st and heading up to Glacier. We'll be coming up 93 to Missoula, going east on 200 to 83N, to 2E to 89N, to Saint Mary, then the Going to the Sun Road westbound to West Glacier and staying in Columbia Falls that night. My question is to those that live and ride in these parts, how much traffic should we expect taking this route at that time of year? Thanks.
