We have rented a huge house in Yellowstone in June, with my siblings and their families. We want to drive, to see the states, and to save money. We are staying in Yellowstone for a week, and plan to take our time on the way to the park, and pretty much drive home in 3 days on the way home. Any suggestions, sights, etc? We'll have our daughters aged 15 and 18 and our son, 8. We love history, nature, beautiful sights, touristy areas....anything! We're just starting to plan, and haven't been to most of the states that we'll pass through. We will either drive our mini-van, or rent one to drive. Thanks!
