I'm sure I've been to Mt. Rushmore at least half a million times, however they've recently added a walking path that takes you very close to the faces. From this vantage point, you can see across much of the Black Hills.
We always stay at The Roost in Custer, SD. Frank & Susan, the owners, are the best and we wouldn't stay anywhere else. We stayed in Cabin #6 four years ago and we requested that one this time too. Unless it's already spoken for, it will probably always be our "cabin of choice"!
