For an Italian guy, he could really sell it.
It was indeed a wakeup call regarding trash. Styrofoam cups that are 5 years old. Plastic bags at least that age. The shear volume of cigarette butts.
We were talking over dinner about some signs to post near the small area where four or five trucks can park overnight behind the building. They frequent the pumps in the back and the businesses in the center, so I don't want to ban them, but we were trying to think of what signs might encourage them to take better care of the area. We provide a porto-potty for the off hours and trash cans, but the porto is used as a trash can and the field used as potties.
I wonder if mild humor is more effective than just a simple insructive sign.
