Burning man might be fun to do once.  The problem is I'd have to take massive amounts of drugs or I would just think it was stupid.
And any multi-day rave breaks down to gift economy after long enough lol.  On the last day of Global you could trade a pack of cigarettes for like $60 worth of designer narcotics.
If any of you really want to go but can't afford tickets, there is some deal where you go early and help set it up in return for free tickets, I know a pretty decent amount of people that do it every year.
