I almost left before Ozzy. Me and my friends were miserable, I was there to see Halford, they were all there to see Crue, so one of them suggested leaving after them and just missing Ozzy. While I can understand leaving after Nonpoint cause there was still a while to go, I told them it'd be stupid to have stood in the rain all day just to leave early and miss Ozzy when we all wanted to see him.
Believe it or not, it actually sort of warmed up during Crue & Ozzy's sets. Whether it was because everyone was enjoying themselves and moving around or that the rain stopped during Crue's set (which it did for a few songs), I don't know, but it was nice to not be cold for once all day.
