for the entire city. reporter: organizers say just a few years ago they were lucky if 5,000 fans showed up for this evented. last year it got a little bit better, 25,000 folks showed up. this year, so many people came here, they had to turn people away at one point. not only that, but a record number of single-game tickets were sold here today. they showed up at the crack of dawn. some waiting for hours to catch a glimpse of the giants. really weird seeing them in person compared to on tv. but cool. reporter: brian wilson, the catcher buster posey, seemed more like opening day in april than fanfest. very, very crowded. the lines are very long for autographs. very long to get in. everybody s pushing each other. reporter: so crowded, that the free event got shut down temporarily to allow lines to disperse. a great crowd all day. reporter: with an estimated 40,000 fans spilling out of at&t park, bars cashed in. obviously a huge boon for the city economically. w
