I found out today that my supervisor is 30. This is the same guy who wore a Marilyn Manson shirt to work yesterday. That might be all I need to know.
There's nothing wrong with either. Early 30s are a great time.
So I take it you don't hold that still going to shows after you're 30 is "pathetic"? (like I was once told by a certain Scotsman.)
Don't the acts age with their audience?
I don't go to shows like you do, but I went to see the Scissor Sisters in Boston 5 years after the last time I went and the crowd had a healthy contingent of middle aged gays so I fit right in.
I've been to plenty of shows with a large contingent of older people, and at least one with a non-negligible number of people who were old enough to theoretically have children who would also be old enough to attend the show (Buffalo Tom), but all were basically for reunion tours of bands that were big 10-20 years ago. However in Minneapolis it is not uncommon for people around 30-35 to still go to the type of shows that are very low or no cover charge because the venue makes all the money off drinks and the whole point is dance around while wasted. That's the type of thing that certain folks clearly consider to be socially unacceptable at that age (as well as ever wearing band shirts for that matter.)
It's socially acceptable in Portland until at least 45.
