We are a family of four (16-yr-old daughter, 13-yr- old sports-nut son). We are looking to take in the "Great Out West" July of 2008. Within 14-16 days, we would like to fly into Denver and leave out of Salt Lake City. In between, we will drive to visit Rocky Mountain National Park, Mt. Rushmore, Yellowstone, Tetons, Jackson and maybe Salt Lake. I could really use some help with a proposed itinerary: best route, hotels, how long at each stop, best to do's! Any input would be GREATLY APPRECIATED!
