I'm 42 and my boys are 12 and 14. We all like a mix of music, but our house clearly prefers hip hop over classic rock. I'm surprised I haven't seen you guys outside Peden wearing sandals and black socks yelling at people to get off your lawns.
Agreed. I don't like it myself, but it's ironic that a bunch of old men are whining about this doggone newfangled music in a thread discussing how to retain the interest of younger people at the game. Anyone on this board is going to games no matter what. Hint: The music is not for you.
As to solving this problem, it's worth noting that this is mostly a nice problem to have -- at least students come to our games in the first place.
