He found another in New York City at McFadden’s on 42nd street, which is the home base for Bills fans who live nearly 400 miles from home.

Trent even found a Bills bar in the unlikeliest of places -- Boston, home of rivals, New England Patriots.

A map on the team website shows more than a hundred bars where Buffalo fans far away from home can find each other on game day.

Trent knows firsthand how fans outside the city feel; he began his career in Buffalo and is a massive Bills fan.

He calls the fans outside of the city an “underground network” and “every Bills fan knows how to find a bar.” This is because not every game is broadcasted nationally, which is why it is so important to find a place that will show the team's games outside of the city.

“You look for that kinship outside of the city. Buffalo has a strong sense of community,” Trent declared.
