More than 40,000 fans flooded AT&T Park Saturday to greet and cheer the World Series champions at San Francisco's annual FanFest. It was the largest crowd the club has hosted at the annual event that leads up to spring training. So many people showed up that the Giants had to turn away hundreds who were standing in a line about three football fields long that stretched around McCovey Cove beyond the right-field wall. Giants closer Brian Wilson and Rookie of the Year Buster Posey both needed police escorts. Team spokeswoman Staci Slaughter said attendance Saturday was "well more than 40,000" -- comparable to a busy game day -- though she didn't have an exact total because people were spread out from the field to the stands and even to the press box. The FanFest has attracted between 10,000 and 20,000 people in the past.
