"This year’s U.S. Open tracks should be two of the best yet," said Dave Prater, director of supercross, Feld Motor Sports℠. "They’re more technical and tighter than the previous year’s, which will make it challenging and create great parity. There are still some straight-aways and a flat sweeping turn to allow for speed as well. Both tracks should please the fans and the riders."To view each night’s track click the following link: www.ussx.com/track09.aspTickets for the 2009 Rockstar Energy Drink U.S. Open are available at Ticketmaster locations, Carter Powersports (located at 6275 South Decatur Blvd. Las Vegas, NV 89118) the MGM Grand Garden Arena box office, www.ussx.com or by phone at (800) 745-3000.
