Better route out of West Yellowstone up to Two Medicine, we have taken us 191 before & found it a nice scenic route up to I-90, question is, is US 287 as good or better, looking on Google street view,...
Fond memories of Two Medicine, St Mary's KOA and Many Glacier campgrounds. Can't do the strenuous high country hiking trails I used to do in Jackson, Yellowstone and Glacier sad to say. But some of the best in the lower 48 are there. Our National Park system is mainly why I got into RVing in the first place. Of course a two person pup tent worked just fine in my younger days.
