My friend, raceboarder7, is a racer. He also was a football star. Weighing in at 150 lbs., 6,1" he is tall and tiny. During his freshman year he was clipped and tore his miniscus... bad news. He is an amazing racer, i'll put money down that he'll be open class national champion next year in copper. When ever he has a somewhat hard crash, the knee swells to the size of a melon Which also results in either no riding for a week or riding like a pansy for a week, which doesn't help with racing. So just beware.
