Three drivers who compete in the NASCAR Dodge Weekly Series at the Bullring at Las Vegas Motor Speedway will spend Thursday at the Hemophilia and Thrombosis Center of Nevada¿s pediatric clinic for children with bleeding disorders from 10 a.m. to 2 p.m. Thunder Roadster driver Randy Bowman, Bullring Bomber driver Gary Wyatt and Semi-Pro Legends Cars driver Dustin Ash will be on hand to sign autographs and take pictures with the estimated 25 children in attendance.
