I've never really noticed it anywhere else tbh.
At Parra, though, with the media behind us and all the bandwagon fans coming out of the woodworks, you often see people who haven't been to a game since 1986. You also often see people that you wonder how they scrounged up the money for the tickets in the first place...
That's not everyone, mind you. Plenty of young families take their kids to the footy at Parra, too. And it's great. When there aren't dickheads swearing or throwing coins at the players.
