Thanks for the great story, hope you heal up quick. Can you spare some details of the mishap? How high was the jump? How deep was the water, could you see the bottom? There's a secret pond (as secret as a pond can be in the satellite age) not far from my favorite running route. Getting to it requires some fording and possibly tresspassing, so I don't visit often, but have stopped by for a cooling dip on hot days. One time there were some kids taking turns jumping from a boulder 15 or 20 feet into the murky water. They invited me to join in, but I declined, and later kind of regretted missing the chance. Will you make changes to your gear? I carry gauze with clotting agent in my bike bag. A "tactical" aluminium split is cheap, light, and may be a good idea.
