I just got back from Dolores park, where about 15k people watched the World Cup final on a jumbotron. The event was sponsored by this crazy German dude (and donations during the event). My wife got to the park at 8am to grab some amazing real estate right up front, so we were able to hear all the audio and see the ball clearly on the screen. There was a French section behind us and some Italians scattered about, but the crowd just wanted a good game. The weather was flawless, the soundsystem was excellent (from where we were sitting) and everyone was really well-behaved. It was amazing.
