We are heading up to Mt Rushmore/Black Hills area for 3 days and wondering if anyone knows of any good economical places to stay and suggestions on things to see and do beyond the obvious. I know Deadwood has something like 80 casino's. Whats really cool to see there and any suggestions on moderate priced lodging. Looking to be cheap on the lodging but safe and clean. Rather spend the tight funds on fun things to see and do.
