Dude, just over a little over half the country watches the Super Bowl. No way in hell the other 150 million are in bars or all bunched up in someone's house.
Some people don't honestly watch it. That's just the truth.
As far as tickets/pricing goes... 49ers fans are showing up like crazy, Ravens fans aren't as much. But then again, Baltimore is just an East Coast St. Louis, so the folks aren't flying out to N.O. in droves like that.
