I was at the game and it seemed like 1 of only 3 bills fans in the entire section. I had on a home Allen jersey and a Bills hat. My sidekick had on an Allen color rush jersey and a Bills winter hat. No problems at all. A few boos walking into the stadium and in the stands and that was it. Some light heckling back and forth.
Honestly, it felt no different from buffalo as far as fan interaction.
