I would think it could be cool to just walk up to a driver, team owner, promoter, push truck driver, flagman, pit official, concession worker and hand them $100, no strings, with the promise that it be kept confidential and anonymous. Totally random and NOT expected by any recipient. If the word were to get out, the money would stop flowing. Be like a racing "Secret Santa" all season long. That's my idea of fun. Time to buy another lottery ticket!
