You know, I may go just for the entertainment value of it all - the crowd entertainment value, that is. Your points about the boycotters is right on though...it can and will degenerate fast. Don't worry though - my guess is that most of the 'fans' are like a mob riot - lots of noise and pretty scary, but poorly organized and inept with communication and actual planning and execution. In the end they look dumb, classless, and like the laughing stocks they are.
The Wall Street Journal recently had an article about the Eagles fans...ever since they opened their new stadium, the arrests are down and the behavior has been vastly improved. It was handled through having more security, more intolerance, and a modest but fair increase in the ticket prices. The article went on to mention the laggards of the NFL...you guessed it - BILLS FANS. They said the baton was passed...rightly so.
