HOT SPRINGS, Ark. - Toby Keith leads a busy life as a top-selling country artist, the star of the motion picture "Broken Bridges," and the front man in a series of commercials for Ford. Yet he still finds time to be involved in his racing operation, which will be in the spotlight Saturday at Oaklawn Park when Rotary, a horse Keith co-owns with Arthur B. Hancock III, makes his stakes debut in the Grade 3, $100,000 Essex Handicap.
