I'm all for having fun during concerts... and the screamer near me didn't really bother me once I determined that she was an equal opportunity screamer. It was more background noise than anything else... not like that time that I ended up next to 2-3 die hard Radiohead fans at a NIN LITS concert who proceeded to bitch that NIN < Radiohead for 95% of the show. They only shut their mouths during In This Twilight. I only have a problem when the behavior of the people around me is massively disrespectful and/or obnoxious. The crowd on the whole was nice.
