I have been to one Philadelphia Flyers game (against Ottawa) a few years ago. It was alright, but I was too young to appreciate.
I also have been to a Philadelphia Phillies game. The seats were crappy and there was some loud guy behind us running his mouth the entire game.
I have been to quite a few Reading Phillies games and also have been to a few Reading Royals games. Both of which were a lot of fun, and not as pricey.
Have you been to any live sporting events? How was the experience for you?
