I see it frequently, cleaning up the roadsides from the slob's that throw stuff out their windows. In Ocean County it is offered to those with good behavior, a chance to get outside and get some exercise. Kind of a modern day form of the chain gang.
We have noticed trash bags along the road each time we travel down it, and they never get picked up. So it is obvious these individuals are doing it but nobody comes by later and picks them up. At least that is how it appears to me.
