only true festival ive been to is bonaroo in...'07 i believe. Spent most of the time either drinking beer in the beer garden or smoking weed. But i also had nearly a gram each of 2ci and 2ce, so i took some of that, traded some for acid, opium, and cocaine (which turned out to be bunk).
go to alot of outdoor raves though. usually take some acid along, plan on finding someone with k, and always a shit ton of booze and cigarettes. i swear, normally it takes me 4-5 days to go through a pack, and ill go through two packs at a 2 night rave
