We then took the Iron Mountain Road over to Keystone. Iron Mountain Road has three tunnels that give you a view of Mount Rushmore Monument. It also has two Pigtail Bridges built in 1932. These bridges are made of wood and make tight 360 degree turns in the shape of a "pig's tail".
We stopped at one of the local restaurants for lunch then decided to "take in" the National President's Wax Museum. The museum is a self-guided tour with a handheld speaker that plays informational audio about each figure. The wax figures were lifelike, but I think they need a different hairstylist (those pictures not included).
We then took the Big Thunder Gold Mine tour. This mine was a "bust" with only a few hundred dollars worth of gold mined.
