You can legally be naked outside in Portland.

Nobody really cares. It's not the case where I'm from in South Texas but that may be a good thing. They got a lot of cactus, Christians, scorpions, inch long roaches and scorching sunshine in my homeworld, Maybe not so fun to farm nude down there.
 I did like night surfing nude in Texas but the gulf of Mexico has it's own carnivorous hazards.
When you get crabs down there they are literally crabs.
