If you aren't afraid of partially or fully submerged manmade objects under water yet, then you're about to be. There's something so frightening about a giant dam spill well (am enormous HOLE just sucking water down into a deep abyss) in the middle of a lake, or a sunken ship resting at the bottom of the ocean. These things are just right next to you while you swim and it's like, I don't want anything to do with it, please get it away from me.

It may be fascinating, but it's fascinating in a way that gives us the creeps.
