I used to live in quiet cul-de-sac that had just enough parking for the people who lived there
Then, over a period of a few weeks, more and more strange cars would appear parked down one end of the road until it got to the point where the locals couldn't always park in their own street any more.
I did a bit of asking around and it turned out there was a bloke in the next street who fancied himself as a bit of an Arthur Daley*, and was using our road as a convenient car park. Apart from sheer inconsideration of it, it is actually illegal to do this in Blighty. So, after a couple of pints one night, I went out and stuck a note on one of his motors stating "Stop parking your cars down here, or I start throwing stones".
They were all gone the next day. :)
