Burning Man is the largest “Leave No Trace” event and the largest permitted event on Federal land in the United States. As such, it is administered by the Winnemucca office of the Bureau Land Management. The BLM have made a promotional video starring their rangers and a whole host of Burners.
It seems that the BLM have their own volunteer ranger force now too, the Earth Guardians. The video is surprisingly well made…your tax dollars at work. I, for one, like it when cops seem to “get it”. The cops who look around baffled, and pained to be there, kill the buzz for everyone.
