I only do nekid at hot springs and Oregon has a lot of those too.
There is something about sinking into hot water.mmm Our weather doesn't really get warm enough for me to want to go nude outside otherwise. I did go streaking once as a kid, at midnight with my friends, in the fields. Does that count? Am I 21 century now? :P
I always to go Newport or beaches and towns south of there.
