I thought the arrangement of the signs made a statement of its own.
I stopped to take this picture on the side of the main highway through Dover Delaware. Just after I took it, a man came out to ask why I was taking it, as I answered, he kept probing further and further with more questions. He eventually asked for my card, which I gave him, even though he never identified himself. As I was about to drive off he came back to make sure I wasn't going to post the picture on the internet. If he had bothered to identify himself I could have told him that it's a public sign on a public road.
(The flickr location is intentionally inaccurate so I cant be blamed for pin-pointing anything vital to national security)
