There are few things as foul as a Folgers can full of human waste. I hesitate to describe the experiences with them any further. I can’t even begin to imagine how big cities deal with the homeless population. Even a very small number are remarkably destructive. Even out here in America’s armpit there’s been a spike in homeless people. Abandoned structures sometimes become dangerous because of it. It’s a sad state of affairs, but better minds than mine haven’t solved the problem so I doubt I’m going to come up with any solutions any time soon.
