Secret Garden Party 2007
Apparently, the organizers of the Secret Garden Party 2007 in the U.K. went to Burning Man in 2006 and have taken much of the burner spirit across the pond including theme camps, participation and community art, and a brand-free environment to play in. One advantage is a deeper focus on performance stages and live music acts.
Looks mighty fun! Is there a tube across the Atlantic yet?
