Workers were busy in Civic Center Plaza Tuesday, turning it into party central. Mayor Gavin Newsom will present the key to the city to the team during Wednesday's festivities.
Most of the high-rise windows along the parade route no longer open up, so the city is positioning people on roofs to drop 10,000 pounds worth of orange confetti.
Planners expect crowds to line every inch of the route that goes from Montgomery and Washington to Market and City Hall.
"We expect tens of thousands of people, my gosh, it's going to be 80 degrees tomorrow so we can expect even more than that," Newsom said.
There will be a celebration at City Hall at the end of the parade. Details are still being worked out, but Newsom says it will involve Giants past and present.
"The Giants, of course, are bringing out not just current players but some surprises and a lot of folks that are indelible in the minds of Bay Area fans," Newsom said.
Fan Mary Fitzgerald is torn between wearing her "Fear the Beard" or "Let Timmy Smoke" t-shirts.
"I'm definitely coming to the parade at 11; my children go to Lowell High School, I'm hoping they'll be excused from classes to come with me, so Lowell High School, please let the kids out," she said.
The San Francisco police Department says they will have high visibility at Wednesday's events, all officers' days off have been canceled.
Streets near and along the parade route will be closed sometime after the morning commute.
The parade begins at 11 a.m. ABC7 coverage begins at 10:30 a.m.
