When I was a teenager my parents lived next to a vacant corner lot and the punks would run up in the vacant lot and across my parents front yard, tearing up the lawn. My dad and I were putting a hedge in the back yard and uncovered several large rocks. We half buried them in the tall grass of the vacant lot about 5 foot from the property line. Not too long after, we heard the revving engine, squealing tires and then a large thump! Came out the next morning to see the tire tracks across the lawn and a trail of motor oil down the street!
Score! No one drove across the lawn again ... :laughing:
