Preparing for the Olympic Torch Relay in San Francisco

The Olympic Torch has been greeted with protests during almost every leg of the relay on the road to Beijing. In Paris yesterday, it was extinguished four times. Tomorrow it's scheduled to run in San Francisco, where protesters scaled the Golden Gate Bridge to hang banners. On Friday, the International Olympic Committee will meet to decide if the international process should be called off. Meantime, heavy security is being planned in San Francisco.  Marilyn King is a two-time Olympic pentathlete who's planning to run a leg in tomorrow's torch relay in San Francisco.
