JimC:128 Minutes in a local cave. Max depth 11 feet.
Its nice to have literally hours to figure your self out of a jam and not have to worry about deco at all.
My wife and I dived a little cave in Kentucky where our max depth was about 9 ft. Of course we had to swim our gear accross a lake and use ropes to get it up a mountain to get to the cave entrance. The entrance was a knee deep mud puddle at the bottom of a rock face. You slipped into your gear, slid down into the mud and crawled under the rock to get in. the vis wasn't too bad once we were in and there were tons of creyfish. Very silty though. Just touching a rock to tie off a line blew things out pretty good. We went to where the existing line goes through a restriction, which wasn't very far, and turned. It wasn't much of a dive but was definately an experience.
