It shouldn’t be any surprise that D.C.’s white-collar class likes to party at Burning Man. The city’s Web developers, Peace Corps alumni, and all-purpose paper-pushing bureaucrats discovered the world’s most famous desert party more than a decade ago. The bigger shock is how gung-ho some of D.C.’s burners are about it. This year, a local group raised more than $8,000 on Kickstarter to finance “National Treasure,” a 20-foot-tall, fireball-shooting, bubble-blowing replica of the Washington Monument they built at Burning Man. (It was later torched, meeting the same fate as every art project at the week-long festival.) But some don’t even bother with Nevada anymore; they just hit local Burning Man parties, like Delaware’s Playa Del Fuego. Why? They’re cheaper, yes, but they also serve as a respectable stand-in for a festival that aspires to build microcommunities.
