Like everyone posting here, I have been naked in places where there was a bit of a risk. The most daring, in retrospect foolhardy, was ay the Great Wall. I was taking lots of photos and eventually found myself alone, so I stripped and snapped a few quick pics. Nothing especially interesting photo-wise, but it was sort of a rush to be naked there for a few moments.
Two times come to mind.
1. I recently visited some TN friends near me. As I got closer to their house I slowly removed my clothes so that when I arrived I was driving completely naked. I then walked to their front door and waited for them to answer the knock. Of course, as I was waiting a car drove down the street - no where to hide so I just stood there.
2. Posted to Daring Nudists. I stay in a hotel 4 days a week. One day I decided to get ice for a drink. I had to walk down the hallway, get the ice, and then come back. I had a friend who I asked to take some pictures - She only took one. So I repeated it, this time with more pictures. In addition, I took some pics in the elevator lobby and a video of me walking down the hallway. It was pretty exciting. Some pics and the video is posted to my profile.
This summer I plan on taking the convertible out for a naked drive.
