Going to shows alone can be intimidating, but remember that you're always way more aware of it than anyone else. A show like that would be totally fun anyway, whether or not you were with friends, but it would be a drag waiting in line to get in all by yourself. But yeah, I hear ya, cause a few months ago I was always going to shows alone cause none of my friends wanted to go, so I've made new friends who are total whores for rock shows, and now I can always find a companion!
