We did this in 2017. Made reservations for 3 different nights for a 18 day trip- seat of the pants trip. Some of the higlhights: John Deere museum in IA, Rushmore, Crazy Horse, Devils Tower, Little Bighorn, Buffalo Bill museum in Cody, stayed in Red Lodge and drove into Yellowstone, Museum of the Rockies in Bozeman, Glacier Road to the Sun, Kootanai Falls north of Trout Creek, National Bison Range, Badlands SD. That's the highlights and how we did it start to finish. Hope to do it again in a few years.
