Reminds me of the time I visited Penns Cave in PA. It was cool. It’s traversed by boat and part of the tour now is about how much damage running the tours over the century damaged the cave. It’s kinda meta.

My favorite part is when they show you “the chimes” and talk about how tours used to tap them to make a spectacular noise during the tour and how they took millions of years to form but now they’re all broken because we are all dumb monkeys.
