1999 - Beaver Mines Lake. I was prussik climbing, and was suspended about 30 feet above the ground, when the carabiner on my harness snapped (sounded like a gun going off). It took the guys running the prussik climb a while to find a ladder long enough to reach me, during which time the foot in the harness went completely numb, and the numbness started working its way up my very taught leg, making it harder and harder to put weight on it. The only other thing holding me up was the grip of my bare hands on the rope. People on the ground afterwards said that by the end I holding on so tight that I was hanging almost upside down. In any case, once they did get a ladder to me, I was put in hospital overnight with my hands completely bandaged up (bad rope burn) and treated for shock.
Had I fallen, it likely would have been lights out.
Random prussik climbing image from a google search, though this lucky sod has two foot holds where I only had one.
