The first item on the agenda was to visit the Mammoth excavation site in Hot Springs - an active palentological dig site with the largest concentration of remains in the world.  After a short background movie, we were guided through the site with engaging information.  In the afternoon we took a drive through Custer State Park - 71,000 acres and the natural home to all kinds of wildlife, most notably over 1300 buffalo. Windy roads and tunnel views of Rushmore. Downtown Rapid City, President sculptures, memorial park, Berlin Wall.
