I gotta do some bragging on my wife here. Bad as it turned out, up to this point she displayed her finest riding to date in negotiating this rock pile. Then, for some inexplicable reason the bike made a full-throttle left turn off a rock, then launched off the trail. She let go of the bike just before it went over the side, then performed a perfect piledriver head first from maybe 10 feet or so above into the smaller boulders (beneath her bike in the pic). From our vantage point I was fairly certain I had become an instant widower. The getoff looked bad. Real bad.
Our new friend Don and I were watching from maybe 100 feet below. We scrambled up to her location, and she was not moving. I started taking inventory, not allowing her to move, insisting that she operate first fingers, toes, etc. Finally I asked her if she could move her head. A bit irritated by the question, she said "No!", and my heart sank.
What she meant was "No, Jerkweed!. I can't move my neck because my helmet is wedged between these two rocks! Are you blind? Quit playing paramedic and get me outta here, you idiot!"
Both the worst and the best moments of my life within seconds of one another. We extricated her helmeted noggin from its "wedgedness", she got up, walked it off for awhile and got on with life.
Her knee's gunna be a little jacked for awhile and major portions of her anatomy are presently the same hue as her bike ( which was spared once more by the grace of TCI) and the story had a happy ending courtesy of these fellers:
The other pic was me ripping on Ronnydog's misfortune just because I CAN.
