Yeah, people around here are brutal when it comes to these signs. You diligently put the signs up and the next day they are completely gone or crumpled in the gutter. You try again and people just ignore them and park there anyway. It can take 3 hrs. for a DC tow truck, but they can at least ticket pretty quckly. It’s a good day when you can actually get a truck parked in front of your house during a stressful time like a move.
