Just read this in Davey Coomb's RACERHEAD over at RXO. Sean was (is) a fast guy from Southern California that I used to watch crush the locals at tracks like Perris Raceway and Starwest a few years back. He was last racing with the Star Racing Yamaha team, and apparently, has decided to give it all up "... to be an actor or something." That's according to what I read at RACERHEAD.
Sean, do what you like. Just know that I, for one, appreciated seeing you ride when you did. Good luck and best wishes.
