** FILE ** Sam Hornish Jr. sits on the pit wall before the start of the final practice session at the Indianapolis Motor Speedway, in this file photo from May 27, 2004. Defending the Indianapolis 500 title will be tough enough for Hornish, but he says he'd like to win twice on the historic 2-mile oval this year. Hornish, who already has driven in two NASCAR Busch races this season, said Wednesday, March 14, 2007, he likes the idea of trying to drive in both major American races at the track, Indy and the Allstate 400 at the Brickyard.
