I am taking a roadtrip in June from Minneapolis to Yellowstone National Park. Although I may have company, I also might be doing this solo- very exciting nonetheless!

I am looking for itinerary items to break-up the long roadtrip. I will be going through Bismark, Miles City, and Billings before reaching my final destination of West Yellowstone, MT. Any suggestions for stops or attractions along the way or once I reach Yellowstone, would be much appreciated! Thank you!
