Did you ever notice the similarities between crop circles and the Department of Public Works? Crop circles mysteriously show up just like those day-glow orange plastic cones you see out in the street. The DPW goes out into neighborhoods and randomly paints bright orange circles and triangles on pavement never to return again. What do they mean?These random street markings just show up exactly like crop circles. Do you think the city is trying to tell me something just like the aliens?
