Pele bites! We were out in the lava beds, heading towards an outfall, not allowed, but at least get closer.. I stopped at the last porta potty, then to catch up started running a bit... As I hadn't ran in a while, naturally I tripped.. BAD place to trip.. As I headed down, hands out, but my right knee tool most of it... Yikes.. Like landing on a sharp cheese grater! I got up trundled on, but the bleeding made me stoip, have a look, big area shredded, it's getting dark, and we're miles out... Rent car absorbed a bit, but we found a little clinic out there, they tool me in, scrubbed the crap out of my wounds, patched my up... Tried to pay them, the folks would not take a dime, check CC, nothing. They either didn't want to mess with paperwork, or whatever, but they were great. Joking about not taking any hawaiian lava, even imbedded home... So no snorkeling, and a bit still on the plane home to the mainland, but good memories from out there...
