I really do hate that.
I went to Ozzfest yesturday and it was a pretty entertaining show. During Static X they were throwing grass, dirt, beer, cups, water, pop into the air and it was hitting other people. I felt kinda bad because one of the head roadies came out and shouted at everyone, cos someone got hurt in the front.
Like I know you should expect this kinda of behavior when you go to a heavy metal festival, but come on! There are pregnant...
