M Otis Beard sez, "A bill gaining support in the Nevada State Assembly would make Burning Man hands-off for state and county law enforcement officials, and subject only to Federal authority."
Each year, the local sheriff has been jacking Burning Man for increasing per-head fees, and the county's conservative lawmakers have been passing silly-season unconstitutionalities, like a law prohibiting a man from being naked in the presence of a child. It's combination of revenue generation and garden-variety harassment, and there had been rumbles about the festival taking up local native groups on an invitation to move it to Paiute land where the county wouldn't get a say.
“Earlier this morning, the Chamber supported AB 374 in the Assembly Government Affairs Committee. This bill, pushed by Assemblyman David Bobzien, came about because of threats by some rural counties to start charging local permitting fees and increasing costs for the Burning Man festival that comes to the Black Rock Desert every summer. This bill would prohibit any local government from interfering with a federally-licensed event on federal land. We strongly support this concept because of the enormous positive economic impact that Burning Man attendees have on our region.”
Some of the problem stems from the fact that Burning Man is held just over a county line; all the on-the-way spending done by burners takes place in Washoe county, but once you turn off to head to the playa, you're in Pershing county, and that's also when the ban on (most) commerce begins. So the county doing the legislating has no real financial stake in the festival continuing. So the local law gets to screw the neighboring county, threatening its one of its major source of economic activity and win points with the voters by harassing hippies.
