AMA Pro Racing press releaseAMA Pro Racing and Kenworthy's Motocross Park have been forced to postpone this weekend's AMA Chevy Trucks U.S. Motocross Championship event due to extensive rain and threat of flooding. The event, originally scheduled for July 12 and 13, will be tentatively rescheduled for Sept. 6 and 7. AMA Pro Racing Director of Competition, Merrill Vanderslice says the postponement was a joint decision between AMA Pro Racing and the event promoter. "Don Kenworthy informed us of the situation with the track and expressed concern about their ability to hold the event," said Vanderslice. "The incessant rains, combined with the threat of severe flooding from the nearby Great Miami River, made it clear that we'd have to postpone the race. There's simply no way we're going to be able to park the team trucks and safely get spectators in and out of the event under these conditions." According to Kenworthy, the track is currently under about two feet of water with no way of knowing whether or not the water would recede by race time. The rescheduled event will now be the season finale.
