In this photo taken Wednesday, Sept. 1, 2010, Burners show off their costumes as the man keeps watch in the distance during Burning Man 2010 in Black Rock City, Nev. For one week out of the year, a portion of the Black Rock Desert is transformed into a thriving diverse city known as Black Rock City, the home of Burning Man. The massive Festival takes place on the barren remnants of Pleistocene Lake Lahontan, which is now commonly referred to as the playa. (AP Photo/The Reno Gazette-Journal, Vince Alonzo)
