You Did WHAT?

I recently sent around this little, fun survey that I got in my email. I don't very often do that but this one was cute and funny and I thought it would be interesting so I sent it to a few friends.

One of the items to check was if you had ever been skinny-dipping outside. I left it blank. I never have. Inside, yes. Once. In college. Never outside.

But here's the really interesting thing. EVERY SINGLE PERSON I SENT IT TO HAD BEEN SKINNY-DIPPING OUTSIDE.

I was really surprised. And curious. Where are all these people swimming that you can get away with doing it naked? When did this happen? What was the situation? My brain is just a-whirl with questions.

So. Have YOU been skinny-dipping outside? Tell me about it. Please. Stay anonymous if you want. I'm just dying of curiosity here.
