Jim Pomeroy, a great guy, a fast ex-racer and the first American to win a motocross Grand Prix in the modern era, has died. There's more information here at Racer X Online, as well as a retrospective written by Budds Creek Raceway owner Jon Beasley, that originally appeared in Racer X Illustrated in 2002. Motocross Action online also has a very good writeup here, that includes the picture you see above.
Godspeed, Jim. And thanks for racing for us.
