Some folks can't understand why anyone would go to a college football game, standing outside for hours, dealing with crowds and security, paying $10 for a bad hotdog and $15 for a warm beer.
Or some TS concert. Or some soccer game.
Humans like being "confirmed", in a crowd of like minded individuals who say "YEAH!!! FIGHT!!! USA!!!" a lot. It's inherent. Then "we" go home thinking everyone is like us.
