I was fortunate to get an off-season tour from "Carter," one of the cave experts who loves caving so much he even got married there! It wasn't too crowded so we could "rush less" (sorry). This cave is long and has a huge variety of narrow passages and wider areas and the famous "big room." We got both the scientific explanation and the sociological explanation about how people's attitudes toward caves and conservation have changed over time. Carter made comparisons to other Black Hills caves also. Even if you think you are not interested in caves, this is a cool and refreshing break, and you can skip your daily Stairmaster since there's lots of stairs. If there is one thing I would change in the cave it would be to nix the garbage cans. All in all though, it's a nice way to spend the afternoon.
