I didn’t even know this, but it’s perfectly legal to be naked in Washington:
bq. Under state law, public nudity is not illegal unless it is an affront to someone else or causes alarm, Potter said.
Six (six!) people complained about a protest of naked bicyclists riding from Gas Works Park to Seattle Center so a proposal to ban public nudity was put before the Seattle Parks and Recreation. “It was rejected”:http://seattletimes.nwsource.com/html/localnews/2008393671_parks15m.html.
Even though public nudity has been legal forever without problems, this could have been yet another case of a few people scared of something harmless using the government to force their personal beliefs on everyone else. But Seattle refused to be bullied by these extremists. Good for Seattle.
