Motocross racing has a rich heritage across the US, but Unadilla Valley Sports Center in New Berlin, NY is one of the most storied facilities in all of American MX lore. The AMA Pro Motocross Championship is coming to the grassy hills of the East Coast for Round 9 to celebrate the track’s 40th anniversary. Chad Reed and the likes will compete for the opportunity to add their names to the record books. To add some additional interest to the event, promoters are going with a retro theme this year. It will be cool to see the racers and thousands of fans with old-school stuff to show their support.

The Alliance of Action Sports has posted a way-cool photo gallery of racers throughout the years leaving their knobby marks at Unadilla. Check it out at allisports.com.
