-Cameras: In general the shows that do allow cameras allow disposable cameras or small personal (non-professional) cameras that do not have large detachable lenses. As this policy is determined by the artist, the camera policy varies from show to show.
Nice pictures. I would have loved to take some but my sister had the camera and took it to work with her. She got there as soon as the main stage started so I only have a couple but not as good as yours.
I drank plenty before I even got there and after all the mosh pits I was in I didn't give two shits about drinking anymore. All I did the rest of the time was drink water or walk around the water fountain things getting my shirt all wet. I guess if I would have just stood around watching the bands play I would have kept drinking but I don't think that would have been as fun.
