Ahhh, now I see why you weren't ready to dive it. LOL 41 degrees, 25 feet, hell....add a 4 knot current and that sounds like yesterday to me. Except I was bringing up old sewer pipe instead of treasure. Plenty of divers can handle that sort of thing, I'm in South Texas right now, but will probably be in Maryland for a few weeks before long. I'll PM you if no-one else is willing....Wayne will do it for sure.
Sounds more like a cavern dive rather than a cave dive. The difference is that you can see the entrance in cavern diving. Special training and equipment is needed in cave diving.

I have me cavern and cave certification and the gear but sounds too cold for my old bones. Is this straight down or is penetration angled? Location? %?
