Welcome aboard the RoadTrip America Forums!

I'll start the discussion by noting that your proposed (very general) route is already 500 miles of so longer than it needs to be. The more direct route would be up through Denver, Salt Lake City and Boise. So presumably there is some reason that you are choosing to go 'the long way around' and it would help people immensely to know what your thinking is in choosing the route you have. That in turn will give them some idea as to the nature of your trip and the types of places, attractions, and roads you'd like to include in your itinerary. The other thing that would be of immediate concern is whether this is a one way or round trip. I also suspect that you'd like to schedule at least one or two stops for the fossils, errr- parents. If you've read many of the responses other posters have gotten, you'll know that we don't 'do', or even believe in generic 'best' routes or attractions, and that the more you can share of your own ideas and interests the better we'll be able to help you.
