Zone Trip
What is a Zone Trip?
We stopped and got out of our vehicles. Michael took a stick out of his car and walked along, marking a long, straight line on the playa floor. This was an old Cacophony tradition of entry into an unknown territory. When the line was long enough to accommodate everyone, eighty-nine people joined hands, and as one, stepped across the line and into The Zone. (source - scroll all the way down)
It is the entrance into a different world. An alternate reality. One that diverges from this one, in minute, yet instrumental ways.
It is also know as a Temporary Autonomous Zone, as defined by Hakim Bey. (read the book)
