I went to a Super Bowl once....no need to ever go again. It's a game. I'd rather be home with my friends enjoying wings and beer for 1/10th the price.
Don't get me wrong, it was a fun experience, but if I never did it I don't think my life would be any worse. Granted my team didn't win, so maybe that would have changed things.

I have never been to a Super Bowl but this is my view of going/not going. It would be nice to go once for the overall experience but if I was really interested in watching the game I would much rather do that from home. The NFL is built for TV now. Too many commercial breaks, stoppages, etc for the people at the the game. They aren't as noticeable watching on TV and you get a much better view of the game.
If my team ever makes it back I would much rather be at home to watch the game.
