Anyone going to their コンサート in NYC on Dec 3?

So I live in NY and really really want to go, but thing is my フレンズ are all in college and seem too "grown up" to go see a boy band (their words). Do あなた guys have any ideas of how to meet other ファン (on here maybe?) または would anyone be interested in going? It's on 12/3/2012 in Madison Square Garden.

Thanks & appreciate all your アドバイス & answers!
