The music - Yes, I was, am, and forever will be a band geek. I love the sound of marching bands and all the brass and excitement and the drums. There are lots of good memories in those sounds. I have to fight the urge to get up and dance to "Land of 1000 Dances".
The food - everything seems to taste better when it comes from a stadium! We'll leave the expense of concession stand food and the way it makes you feel afterward out of the equation for now.
The energy - It's hard to sit in a stadium and NOT get swept up in all the excitement of those around you! Even if you will be truly happy no matter who wins, you can't help but get excited when those around you are getting excited, too! I do draw the line at doing the wave, though!
The mascots - They're cute and they're funny. How do you not love them?
The crowd - I love to people watch, and it seems that sporting events bring out special people with special personalities, all of which are endlessly entertaining! Some can be obnoxious (especially if alcohol is involved) but for the most part it's good old-fashioned fun!
