Does "Burning Man without drugs or alcohol" sort of sound like an oxymoron? It did to me last year (but then again, I am an addict), my first Burn when I was six months sober. I quickly discovered I didn't need drugs or booze to have a great time, but I did need the support of others to stay sober in that environment. We had several people move their tents to our camp mid-week because the people they were originally camped with were a little out of control, so if that happens to you, come & see us. Bonus: We're located at 5:30 & Chance, close to Center Camp.
If you're in recovery & planning to stay that way at Burning Man, also be sure to read Sober on the Playa, which mentions our friends at the other two sober camps, Camp Stella (queer & sober, home of the "Queers, Fallen Women, and Plain Crackpots Group") and Camp Hokey Pokey. Best wishes to all for a great Burn!
