CRESCO - The United States Racing Association Casey's General Stores Weekly Racing Series event scheduled for Friday was canceled due to extremely wet conditions.

Nevertheless, Cresco Speedway remains revved up for Tuesday's big event.

NASCAR Nextel Cup stars Clint Bowyer, Ken Schrader and Kenny Wallace will appear at the Iowa track, as all three drivers will sign autographs between 5:45 and 6:30 p.m. before jumping into their own high-powered O'Reilly USMTS Modifieds. While the trio is best known for circling the country's top superspeedways, all three cut their teeth on dirt ovals in the Midwest.

Bowyer has racked up more than 200 wins and numerous championships during his dirt track racing career, while Schrader started out driving open-wheel cars and won in every division he raced, including two USAC championships.

Wallace, meanwhile, has already achieved victory on dirt this season, winning in Barberville, Fla., in February and at the Peoria (Ill.) Speedway on May 23.
