You guys seriously need to go to a concert. Not some rinky dink local thing, either, go to a BIG venue. It's a huge party with a live band. Yeah beers cost like $8 a pop, but that's why you get hammered while you tailgate before the concert starts.
I can't stress how fun the whole concert experience is. I went to my first concert 2 years ago when I was 18. Saw Tom Petty. Great times, man.
