Here is a link to Hunter Williams home page. Video link at lower right.  Hunter is a 15 yo that now races 250A. he is very quick.  He started two rows back from me. ( 2 minutes) Makes me look slow, Although I feel fast to me
The camera angle is a bit low, his father, Jeff, was trying a new mount on his helmet.
