Broken shoulder skiing.
Snapped ACL being hit by Cadillac.
Seven fractures in right foot from landing sideways off an 80 foot double in motocross race.
Three cracked ribs going over the bars in MX practice.
Broken ankle in Gus Macker tournament (passed right out, it was neat

)
I'm sure I missed a few. Now that I'm 80 pounds over weight I tend to hurt myself much less in athletics
Edit, almost forgot a neat one.... Another MX crash, but not on a track. Went over backwards deep into 5th gear(maybe 50-60 mph)while doing catwalk down a dirt road. Slid off the road and cracked my melon (w/helmet) on a mailbox post rendering me night-night. I had major leg muscle hanging out of my leg and lost about three years of memory. It was days before it all came came back. In the beginning I would lose my short-term memory every 30 seconds or so. Very strange indeed. I "woke up" in the CatScan tube and freaked out which was also neat

Many other neat memory loss stories on that one. MX bikes are great and I'm sure I'll get my boys racing too
