The worst we did as stupid teenagers was throwing a laso at trailer balls on trucks passing by in town on the 4 lane strip. It just took that one first guy to catch one to realize the rope burn and missing laso rope. I've often wondered what the family thought when they got home with a rope dragging from the ball on the truck.
Well, me and my friend John came up with the idea of launching shopping carts using my El Camino. He would hang onto one out the passenger window, I would get up to 20-30mph. He'd let go, I'd stop the beast. The things those carts did when they hit curbs, walls, trees, sidewalks, jumping across the 4 lane road at 2am. Glad there were no cameras back then, we destroyed alot of carts.
