Couple of things we wanted to see in Keystone the town right next to Mt. Rushmore. 1) the National Presidential Wax Museum (or so they call themselves) 2) the Big Thunder Gold mine 3) Borglum Museum.
The presidential wax museum was worth the time.
The wax figures for the most part were amazing and they had a story/information on all the presidents.
The Big Thunder Gold Mine was fun and interesting.
The Borglum Museum was a bust for us, it closed at 3:00 with the last tour starting at 2:00, we got there about 3:15.
and we did the night time lighting of Mt Rushmore.
