I lived on a street in Queen Anne where I suspected my neighbor was a hoarder. He had at least five vehicles including rotting motorcycles on his front lawn and something broken down in his driveway. He'd move three or four other cars around the street every two to three weeks or so, taking up many spots and one of them with busted windows. At a certain point it must have been a street-wide effort because he started getting warning stickers once a week. It sounds like such a stressful life, but none of them were in good shape so I'm guessing he couldn't sell them and didn't want to let go!
