Hi, I am planning a road trip this summer, The Itinerary is not concrete by any means. I am not sure how many people will be going, but we may be able to stay with friends in Billings Montana, Denver Colorado, and Minneapolis MN. The route that I have so far is posted below. We will be a bunch of college students with a limited amount of money. We plan on staying in campgrounds in tents. Hopefully we can limit the time it takes also. Maybe a week to a week and a half. Any ideas for destinations that were not included? We need some guidance for the long route between arizona and chicago. We want to visit the grand canyon, yellowstone, six flags (chicago), and Bryce canyon. ANy ideas?
