Definitely go to West Yellowstone, MT! It's a wonderful little town on the west side of Yellowstone NP. We're going there this next weekend and then on to Glacier. Never been to Glacier, but have been in West Yellowstone a few times and it's a favorite. They have a wonderful summer repertory theater, the Playmill Theater, there too (where we'll be going to see "Seven Brides for Seven Brothers...a favorite of mine!). The Running Bear Pancake House is a "don't-miss" kinda place. Yummy food and friendly folks!
