If race horse "California Chrome" wins the Belmont Stakes tomorrow to complete a Triple Crown sweep, then this could help the racing industry. The industry will try to turn attention attracted by the first Triple Crown in 36 years into a revival of the sport's popularity. Santa Anita Park executives hope a crowd of 30,000 will show up Saturday to watch the Belmont on TV screen. Betting at Santa Anita Park has declined 40% between 2002 and 2011 before ticking up the last two years.
