Great idea, Donna. And since I just checked Yellowstone lodging to find everything for the day I would need in June sold out, it'll be a better option to really see the park. I am still going to pitch the idea of driving through though. I visited Glacier NP many years ago as a drive through and still have memories of the mountains and moose and bear we encountered.

I think I've got plenty for us to see on the western end of the trip with sights of SD, Yellowstone, ghost town near Philipsburg, MT, but still trying to find what to see between the SD border and Cleveland. Thoughts? I remember that area as being a sea of corn...there must be something a bit off the beaten track?
