‪Rapid City has long been considered one of the gateways to the West, and its rich cowboy and Native American heritage is the result. Visitors won't want to miss the area's mammoth outdoor sculptures. There's Mount Rushmore, of course, but work also continues on the nearby Crazy Horse Memorial, which will be the largest sculpture in the world when it is finally completed years down the line. Among the many local attractions are the scenic Black Hills, several nearby cavern systems that offer guided tours and the South Dakota Air and Space Museum.‬
