My wife and I have decided to do Sturgis in August. We'll be out there for about 5 days and I'm looking for advice on how we should spend our time. There are concerts we'll go and see. We're trailering the bike out and will want to do some riding in the Black Hills. She's never been to that part of the country so Mt. Rushmore and Crazy Horse will probably be on the list. Outside of that our options are pretty wide open. What should we definitely go and see? What should we avoid?
