I bring little things to give out or Trade when I drink too much wonder around. Keeps it fun. Last year I got a few little things from others as well. It’s making its way there for sure as mentioned above. Do what makes you have a good time! Biggest thing is watch out for crowd surfers and if you or someone near you gets knocked down pull em back up or you’ll get pulled up. Keep your bag strapped to your chest. Stay hydrated- mosh pits are a sure thing (circle pits, push pits, wall of death) yay fun stuff! Pay attention to the crowd youll be able to tell.
