The return of the IMCA Modifieds and a 200-lap Grand Enduro will highlight racing action this week at the Bullring at Las Vegas Motor Speedway. The IMCA Modifieds are returning to the Bullring following a two-week break. Intense racing will resume this Saturday night with a feature 25-lap event. Rich Attisani, driver of the No. 777 Chevy Monte Carlo, holds a 74-73 lead over Ken Kulikowski in the point standings. The longest race of the night puts the Bullring Bombers on center stage. Darren Rollins, winner of the 2002 championship, has a two-point advantage over Troy Rawling in the standings, but this 200-lap endurance test could change the standings in dramatic fashion. Legends, Late Models, and Chargers also are on the racing card this week. Chuck Trickle took over the points lead in Super Late Models with his win this past weekend over 21-year-old Chris Clyne. Super Late Models will return to the Bullring for more racing action on Saturday, May 24. Scott Gafforini trails Trickle by two points, while Mike Cofer trails Trickle by eight points. Other point leaders include: Tom Youmans (Chargers), Rick Rogas (Masters Legends), Michael Fredericks (Pro Legends), Taylor Barton (Semi Pro Legends), Dave Green (Thunder Roadsters) and Kyle Huender (Bandoleros).
