I'm very new to this and am planning our first RV trip this summer. We KNOW we are going from TX to ND. We want to make stops along the way up there, and we definately would love to venture over and hit Yellowstone. But what else is around there for us to see? How do I begin to find out what might be "in our path" so we don't miss something for lack of information. Thanks for all the help you can offer!
