PK, here is what I found out:
Our friend Matt, whou is about 6 feet tall and 135lbs was riding it and from what people that were there said, it looked like he locked the front up after the finish line and washed it out under him (Matt). It slid for about another 3-500 feet and Matt is pretty rashed up. One leg for sure, hands and knuckles. Went to the hospital with a suspect broken ankle, but was complaining his hip was hurting also.
Evidentially he wasn't feeling too bad, as he was concerned with how fast he went!
