This was a difficult shot to get. I didn't want to look like I was trying to get shots inside the porta-potties. But I really wanted a shot like this for the challenge. Then, I saw this dog. The perfect opportunity. I was obviously taking a picture of the dog. Fortunately, also, people waiting to go tend to keep a certain distance away from the porta-potties. It's kind of humorous, actually, if you ask me. The trick then was to capture the moment when all the doors were shut. I think this turned out really well, if I say so myself. I think the dog makes the picture.
