neighbor hood pranksters???

I Found on the way home a 2 step fold up latter, a garden shepherd hook, Legs off a high chair, some iron poles, a cd player and some other stuff. I go out front to put the stuff into the other truck thats parked in the street. Someone put a bunch of broken X-mas ornaments in the truck. The big shiny softball sized ones. Ok??? Im thinking, Thanks who ever put these here but those are plastic. Might be the skateboarder kids,maybe a joke that someone thinks their funny. At least they tryed to help I guess
