As part of its pre-event facilities inspection, Lowe¿s Motor Speedway officials will test the speedway¿s massive sewer and water infrastructure with the second annual Great Speedway Toilet Flush Tuesday night, May 6, at approximately 7:15 p.m.

The ideal test would be to flush the speedway¿s 3,000-plus toilet fixtures at the same time, simulating a ¿peak demand¿ on the systems.

Speedway officials are inviting fans to watch NASCAR Craftsman Truck Series testing and lend a hand with the flushing. Instructions will be given to the fans sitting in the grandstand area that wish to participate.

Official ¿Royal Flush Society¿ T-shirts will be given to the first 500 participants.

ASCAR Busch Series testing runs Tuesday from 8 a.m. to 3 p.m., while NASCAR Craftsman Truck Series competitors test from 4 p.m. to 10 p.m. Grandstand admission is free to the general public. Fans may enter through Gate 5B, next to Smith Tower.

The on- (and off-) track testing is in preparation for Coca-Cola 600 Month activities which begin Friday night, May 16, with qualifying for The Winston and the inaugural running of the Hardee¿s 200 and conclude Sunday night, May 25, with the 44th annual Coca-Cola 600.
