My family is planning a 3 week trip to Yellowstone in June of 2014. We want to pass through the Mt. Rushmore area on the way home or there. We live in Southern Indiana. We will be taking our new travel trailer. So we can stay in any campground. We prefer more of the state park feel for longer stays. The private parks tend to be more crowded. We don't mind staying a night in a park like that, but for our longer stays to would like to not be on top of one another. Looking for the highly recommended CG's and the ones to stay away from too! Any help would be appreciated!
