JeffG:Think Big. Only one dive.
Wait tell you get diagnosed with fatal cancer and do a bounce dive on the Titanic.
Pathfinder:Youch! 12,500'. I don't think there will be any bouncing there.
At least not a bounce back to the surface!
Although the Titanic sounds intriguing, I think I'll go with Wakulla. I think it'd be easy to get lost in there.
