Have you ever been in a caver? I just explored the Hoggatt Cave and I loved it!
There were surprises everywhere you tuned and at the end they sang a song that said "We don't talk about guano-no-no-no." Guano is bat droppings that makes good fertilizer, but after they stopped singing they said "And here it comes." And they had like spray bottles with water in them that made it feel like their droppings fell on us.
It's always nice to see how others perceive our presentation.
