Posting that it is illegal to hike nude when it is not, is different than people on this board insisting that the no camping rules at the hot springs be followed. Those rules are real and clear, and they help preserve the springs.
I've seen lots and lots of folks obtain tickets for camping at the springs; also for what Jobe calls "medicine"; I've never seen nude hikers experience any problems, because what they are doing is not against the law. I have also seen one of the Rangers nude hiking! (Perhaps on his off hours, but still...)
