Standish, Michigan

It's two p.m. on a workday, and the casino parking lot is completely full. Hundreds of people have come for the $20 gambling coupons offered to those willing to donate blood. Turnout for the drive was "above and beyond" expectations, says Frank Cloutier, a spokesman for the Saginaw Chippewa Indians, who run the 800-slot complex. The nurses are already turning people away two hours before closing, and they will soon run out of blood bags.
