We are planning a trip out west (Wyoming, Montana, Colorado, ????) from Kentucky next summer. Any absolute must sees and great campgrounds for motorhomes? We are going to tow a car, so would like to stay in one place for several days at a time. Also, we are going to fly our son, daughter and 7 year old grandson out at some point. Anyone have a good spot to stay that will be a great family spot and lots to do for a 7 year old? Is there a campground with horseback riding or ranch type activities?
