I've had a lot of those, but I think the worst was actually when I was racing in high school. We had a GS race at Purgatory. It was on a really flat run called upper Hades. The finish area was just before the top of Lower Hades which was a really steep bump run, so it basically went from flat groomed to severe drop off into bumps.
I was a skinny little terd so I sucked on flat courses, and as I was getting close to the finish I knew I had a lousy run. I had screwed up on a few turns and was practically poling along, so when I went through the finish I was doing throwing the typical " I Suck " tantrum. I wasn't paying attention and I looked up and realized I was about to go straight into the control fence. I made a little move and managed to make it out of the exit opening and started turning up a catwalk. There was a beginner coming down the catwalk in a huge snowplow. I couldn't go high so I decided to try to drop onto Lower Hades and try to traverse across the bumps to stop.
It's funny how under those circumstances I thought I was going way slow, but I was actually still going pretty fast. As I went off the road into Lower Hades I knew that this was going to be very bad. I guess it would have looked like an unnatty misty, long before anyone did one. The last thing my friends saw of me was the bases of my 210 GS's tips pointing up.
I ended up flying head first about 75 feet down lower Hades wearing my stupid skin tight GS suit.
Luckily I landed on the backside of a mogul. It hurt but I didn't break anything. If I had come down six feet shorter or six feet further, I would have hit right on the face of a mogul, and I don't think I'd be alive now.
Nice story Hansel, but I'm not creative enough to make that up.
