lol....I came across this thread while researching if my collar bone is going to permanently stick up. Guess I found out the answer is yes!
My story: August 2010. Won a work trip to Lake Tahoe, took a close friend of mine. We are staying at the Ritz Carlton in Truckee (North Tahoe) and are looking for something to do. We look up the mountain and see a bunch of dudes going up the lift with bikes.
We talk to the biking guy and he suggests if we want to take it up a notch, we do downhill. This is after a several red bull and vodkas, so it sounds like a good call. Mind you I've never mountain biked before and had limited BMX experience up until I was 16 (10 years ago).
I figured things were going to turn out bad since I kept on landing on my front wheel and couldn't fix it. I made it down about halfway before I flipped over my handlebars, not sure what happened since I blacked out.
I somehow made it down the hill and thought I dislocated my shoulder. Had some really nasty road rash all down my back too. Since it was the first day of the vacation, I chose not to go to the hospital and just party it off. It really sucked.
Finally got back home, went to the doc. Grade 3 separation, borderline grade 4. I still feel it and need to get back into lifting after a few months off. Oh, and I'm never touching a freaking mountain bike again...lol.
