Praise Scutaro, the Giants swept the World Series last night. And San Franciscans, loose after a brilliant sunny day in the city, with ample practice from the Giants’ victory two years ago, and half dressed in their Halloween costumes, acted accordingly. Photographer Charles Russo was on hand to capture everything from the cheers in Civic Center Plaza to the fires that were lit on Mission Street late last night. Not pictured: champagne geysers, the orange-and-black celebration of choice in 2012.
