BLACK ROCK DESERT, Nev. (AP) — An unusual late-summer storm turned a week-long counterculture fest into a sloppy mess, with tens of thousands of partygoers stuck in foot-deep mud and with no working toilets in the northern Nevada desert. The gathering in the Black Rock Desert about 110 miles (177 kilometers) north of Reno attracts nearly 80,000 artists, musicians and activists and for a mix of wilderness camping and avant-garde performances. More than a half-inch of rain fell at the festival site on Friday, the National Weather Service in Reno said, with more coming Saturday and Sunday. Organizers closed the festival to vehicles after one death was reported. Officials provided no details of the fatality.
