Saw something similar with my own eyes, but it was a few years ago when not every household, including myself, had a digital camera. I was at work and didn't even have a camera anyway so I didn't have a chance to take a pic. These guys were putting down new lines in a new section of parking lot. In one area (the fire/emergency area?) they had the crossing lines and what was supposed to read "NO PARKING" painted on the blacktop. Only these guys spelled it "ON PARKING." haha
