From a bartender I know who gets a large number of fans on Sunday nights, there's a ton of Steeler fans in the area. They're also the most pleasant as a rule. The only other teams that consistently bring out larger than average number of fans are Giants, Cowboys, and Packers.
Thanks for sharing this inside info from your bartender friend. I would have never known there’s a lot of Steelers, Packers and Cowboys fans outside of their respective markets and that NJ is unique in this regard.
