Holy macro, after the whole incident a few years back with the kids trapped in the cave, I had _no idea_ how treacherous cave diving is. Optimistic case is you have to swim straightforward, completely blind, while not panicking, in the dark, using just whatever guide wire/rope you set on your way in. Oh and the water is probably nipple-freezing hard. I'm a purveyor of extreme sports but nope, I'll leave this to the UUVs. Nope on a rope.
