In this Travel Bug Robert episode, Robert travels to perhaps the most American national landmark there is: Mount Rushmore, located near Keystone, South Dakota. The faces of Washington, Jefferson, Lincoln, and Roosevelt carved into a mountain--pretty American. Here's a travel tip: go sometime not close to the Fourth of July. That way you can get an extra dose of patriotism during the patriotic dry season. Or you can go all out and visit on Independence Day weekend, but you won't be the only one thinking of that idea. Good luck with parking.
