About 15-18 years ago my locl authority TROs had parking restrictions in streets that didn't exist. After intervention by "an activist" (me) and internet research (ppp) it was found that a number of roads in New Romney with parking restictions weren't actually on the TRO. Well, not for New Romney. they were included in the TRO for Lydd, some five miles distant. Somebody had perpetuated the mistake by cutting and pasting and posting in the wrong town. It saved me quite a bit in parking fines. Nobody had bothered proof reading anything.
