There probably 5000 Bills fans there. Whenever I've been to a Bills game at any of the three Florida teams, there's always a lot of Bills fans. Miami fans aren't the most enthusiastic, either.
Funny how empty Miami's Stadium is. I went to a game there two years ago and they came late and left early, even though the Dolphins won and the game was in doubt until the end. I think it's more about the "scene," than the game itself.
