Nascar's Mark Martin had a son that was the next great thing a few years ago. Seemed like he was racing full size cars at 13. Then it seemed like he fell of the edge of the world. Does his story fit into this discussion? How old was Bill's son Chase when he was in a full size car? I would like to see 16 and under, only race with other under 16 year olds. Have then in a slower class, on tracks at or smaller then 3/8 miles.
