Indianapolis, IN — (May 18, 2013) — Tonight’s TRAXXAS USAC “Hall of Fame” Silver Crown race at Lucas Oil Raceway has been cancelled due to the extended timetable of “Pole Day” qualifying events at the Indianapolis Motor Speedway and the potential threats of thunderstorms in the area. USAC recognizes the historical significance of today’s motorsports events and is disappointed to cancel this race but numerous participants in tonight’s program, including the Hall of Fame ceremonies, are also involved at IMS and those ceremonies would have been severely impacted. Unstable weather in the midwest also has created thunderstorm possibilities for the area. Options for rescheduling are being discussed and will be announced when they become firm.
