An anecdot: when I lived in Manhattan in 2001, I parked near 61st and 1st, between two differing parking signs. I was clearly very close to one, and much further from another, by at least 50 yards. I got a ticket for illegal parking according to the further sign. Being a broke ex-dot-commer, I was furious, so I photographed and measured everything, and put together a seven page report.

After a long while, I got a response back from the responsible agency, which agreed that I was in compliance with the parking rules, and thus they would reduce the fine from $100 to $40. What??
