In our neighborhood, we have a nice rock wall, which is crumbling because a developer cleared the land above it and then the flood last May caused further erosion.* Occasionally, people stuff their trash on the ledges or in cracks on the wall. I know that it is neighborhood children, but this is litter.
*Don't get me started about the horrible flood in Nashville last May. I know that irresponsibility from the developers in the area made the flooding worse.
