Burning Man sounds strange to you - that week long experience of heathenist over-indulgence in the middle of the barren Nevada desert.
I have friends who have been going there for years, and serving the Burners with water for the body, and refreshment for the soul. Rob Mazza, and Scott Evelyn helped start the outreach, and their work has become one of the top 5 spiritual experiences at Burning Man. This is my kind of experience. It is the kind of stuff we have been doing in Salem, MA for 10 years now. I need to get to the Burning Man experience at least once before I stretch out to new outreach experiences.
