Four drivers representing two Cup Series championships, one title each in the Nationwide Series and Truck Series, 157 wins in NASCAR's three national series, plus a full racing progrm for the local stars make up the formula for Shangri-La II Motor Speedway's inaugural "Night of NASCAR Stars" on Saturday, August 7. Rusty Wallace, Kenny Wallace, Matt Kenseth, and Greg Biffle have made firm commitments to participate in the star-studded evening.

Biffle replaces Michael Waltip, who was unable to attend due to a rescheduled sponsor appearance. Kenny Wallace, Kenseth, and Biffle will all compete in a match race with top cars from Shangri-La II's ASA Late Model division, while Rusty Wallace provides the expert commentary.

Biffle, the newest addition to the quartet of stars, was the 2000 Craftman Truck Series champion and the 2002 Busch (now Nationwide) title winner. His best finishes in the final Sprint Cup standings were second in 2005 and third in 2008, always driving for Roush Racing. He's made the Chase four of the last six seasons. His 14 Sprint Cup wins, 20 in the Busch/Nationwide Series, and 16 in the trucks give him a total of 50 NASCAR national series victories.

The Race of Champions Tour, the premier paved track modified series in New York State, makes it second appearance of 2010 at Shangri-La II Motor Speedway on Sunday night, August 1. It's titled "Return of te ROC'n Concrete Rumble" but that doesn't mean it's the same show that thrilled a packed house back in May.

As part of the RoC Championship Series, the distance has increased from 75 green flag laps to a full 100 laps around the high banks of the half-mile Concrete Castle. And unlike the May event that was run on a hot, sunny afternoon, the return performance will be under the lights.

Pete Brittain lead until he was passed by Chuck Hossfeld with a dozen laps remaining in the RoC debut race. The veteran from Oakhurst, N.J. sees the need for adjustment to the new conditions, but not radical change to the strategy that came so close to giving him victory in Shangri-La II's first touring series race.

Matt Parsons of Elmira has won the Grand Prize in the Shangri-La II Motor Speedway Pocono Ticket Sweepstakes- two reserved seat tickets plus overnight accommodations for the Sunoco Red Cross 500 NASCAR Sprint Cup Series race this Sunday at Pocono Raceway.

Since race time at Pocono is 1:00 p.m. and Shangri-La II's Return of the ROC'n Concrete Rumble Race of Champions Tour event is under the lights, Matt can do a Sunday doubleheader if he beats the traffic out of the parking lot!  Pocono to Tioga Center can be done in just about two hours at (almost) the legal speed limit.

The remaining winners of tickets to the NASCAR Camping World Truck Series/ARCA REMAX Series doubleheader on Saturday will soon be posted here on shangrila-2.com.
