We are going to be traveling cross country to Wisconsin, Minnesota, North and South Dakota, Montana, Oregon, Idaho, Wyoming, Nebraska, Iowa, Illinois and Indiana. If anyone can please tell us the best places to visit besides Mt. Rushmore, Badlands, Yellowstone NP, etc. we would greatly appreciate the input as well as inexpensive places to stay along the way and any eateries would be nice. Any and all suggestions are greatly appreciated. We have mapped out quite a bit on our own but being unfamiliar with the areas, we can use all the help we can get and THANK YOU!
