A few years ago just before I moved to where I am living now some friends of mine and I took a trip to Lighthouse Beach (a nude beach) in New York. As it was a long trip we stayed overnight at one of the local motels.
We all went to the beach and had a great time there. When it was time to pack up to leave we headed out and saw the National Park Service sign.
The sign was right beside a public road that made kind of a U in front of it. There was a lot of traffic going along the road but it was not so loud that I could not hear the sign yelling at me saying "Take off your clothes and stand beside me nude". I did not want to but the sign kept calling for me to do so, so I finally gave in.
I asked one of my friends to take a picture of me (with my shorts and sneakers on) standing beside the sign. He took a few pictures of me until I saw one I liked. I then told him to stay in that position for a few more shots. I went behind the sign, removed my sneakers and shorts, and then stepped out into position. When I did so he took a few shots of me nude beside the sign. I then went back behind the sign and quickly got dressed.
