I was at 2 of the games VS the Dodgers and if it were not for great tail gates, it would have sucked. Also, the stadium was filled and there were a lot of Dodger fans there. Never saw so many fans of a visiting team as I did VS dodgers. Not with any sport.
As far as Dodgers fans you have a lot of a carry over from the Brooklyn Dodgers years parents who followed the team and their children following along with their parents. You see this all over NY, kids following Packers, Seahawks, Colts, Steelers, etcetera. Poor Jets!!!!
