Wyoming, Here We Come! Another new state for us in the RV! We will end up spending about six weeks traveling the state, so hope to get a good feel for the landscape, activities, people and the culture. Wyoming is a large state geographically (at #10), but is dead last in population. That sounds like many small towns and that is what we like. The Cowboy State has vast treeless plains, the Rocky Mountains, and the national parks of Yellowstone and the Grand Tetons.
