Hmmmm. First, Congratulations and Happy Birthday.
Second, now matter how classess and unknowledgeable you think Browns fans are, they are nothing compared to New England fans (Patriots, Red Sawx, Celtics and Bruins) and even THEY can't hold a candle to Raiders fans.
Finally, have fun and get home safe! If all goes as planned, you can just stay till the very end of the blow out and be able to walk out with the remaining Steelers fans.
