Common sense things you should do to add to your enjoyment of the show and those around you:
- Avoid talking/shouting into a cellphone during the show
- Take care of eating/drinking and port-a-john/bathroom trips before the show so you're not running out during the show (it's unbelievable how many fans I see going on beer/bathroom runs during Springsteen concerts in an arena and at a stadium) disrupting the entire row of fans so he/she can get out
- Don't get so drunk that you wind up puking during the show and then passing out
- If you use recreational drugs, in addition to not getting caught, don't get so stoned you puke or pass out
- Don't get into a shouting match/argument with anyone you're going with, it will just ruin it for the group
- If it's a general admission/festival seating, be courteous to those around you and hopefully they'll respond in kind
- If you're there with people that actually want to hear the music, avoid shouting along off-key (or on-key) to the songs (unless others in your group are doing it)
- Given the triple-bill, I'm assuming these groups are going to be playing mostly the hits and not new stuff, so avoid shouting out requests, odds are they're going to play that song.
- Since it's outdoors, like rallen said, bring some "OFF" or other bug repellent
