But Shea isn't the only hotspot for uncivil activity. Here is a clip of Yankee and red Sox fans pummeling each other. The Sox fan has the edge until gravity gets the better of him. You might argue that this kind of fisticuffs happens often in The bronx. True but this was during the Pope's visit to Yankee Stadium.
I guess the pope part was irony/poetic license? It's obvious that this took place during a Yanks/Sox game.
