We're planning a trip to northern Minnesota in June. I'm wondering what the best route across northern Montana and N. Dakota would be. Tentatively our route takes us from Missoula to Great Falls on Mt. Rte 200, then up to Havre then staying on Hwy 2 across the rest of Montana, to Williston, ND, across ND to Minnesota and then most of the way across Minnesota. Looking at the road map, it looks like staying on Montana Rte. 200 from Missoula to Great Falls to Williston might be a possibility. Any ideas? Thanx in advance.
