SAN FRANCISCO — Orange-and-black clad hordes began flooding the streets of San Francisco on Wednesday for a Halloween Day ticker-tape parade celebrating the 2012 World Series champion Giants.
Three hours before the start of the parade, thousands of people decked out in Giants gear or Halloween costumes were already staking out prime spots behind barriers along Market Street.
Vendors also got an early start hawking everything from pennants to lawn chairs from makeshift sidewalk stands amid the crush of the morning commute.
Fans also gathered at City Hall, where the team will address the crowd after the parade.
Numerous commuter trains were delayed as revelers crammed onboard, and some travelers were turned away from ferry service from Marin County.
With the victory parade coinciding with the spooky holiday, costumed masses were expected to bring an even more festive feel to what city officials stressed will be a family friendly, alcohol-free event.
"This was such a team effort to win the World Series, so we decided we'd get our city team together to make sure we have a great celebration," Mayor Ed Lee said Tuesday as he stood with police, fire, transportation and other officials at City Hall.
After the Giants won the Series in 2010, hundreds of thousands of revelers — from school-age children to longtime fans who had waited decades for a championship — crammed into downtown to cheer on their heroes.
This year's parade route is different than it was in 2010, when a vehicle carrying the "Say Hey Kid" Willie Mays led players and coaches in open-air buses designed to look like cable cars down the same route that Mays' Giants took in 1958 after relocating from New York.
That route started at Montgomery Street in the Financial District and turned onto Market Street. The 2012 edition will begin at the foot of Market near San Francisco Bay and cover about 1 1/2 miles to City Hall.
