My friend used to climb massive pine trees late at night in a park across his street, and place traffic cones on top. No one knew who was doing it or why. Many people thought it was the local council marking the trees to be cut down which upset residents. He started noticing police regularly patrolling the area, but he kept doing it and never got caught. It made the local paper, explaining how much confusion and disruption it was causing the police and local council. He hung the article on his wall.
