I wish it worked that way. East Tennessee is FULL of Christians, and the roads here are LINED with trash.
East Tennessee is also FULL of Busch drinking, cigarette smoking, ignorant rednecks (as is my state) and I bet that's where most of your litter comes from.
When I pick trash up along my roads I find that most of it is Natural Light or Busch Beer cans, Mountain Dew Cans, and cigarette boxes.
