I went to college in the Bronx when the Yankees were winning titles left and right. The old stadium was a short subway ride away, and I went to a ton of games. I grew up a Mets fan, but have no problem with the Yanks other than subway series time.
My old man never cared for sports all that much, but my mom was born in Brooklyn and scorned by the Dodgers as a kid. Been a Mets fan since Day 1. So that rubbed off on me as a kid.
As for the Jets and Giants...I hope a blimp full of diarrhea and broken glass crashes into Met Life Stadium. Go Pats!
