Charley, you have my sympathy. I have had to dig up more than one clogged line due to some idiot flushing a diaper down a park toilet.

In the Maine State Park system, we have lovely anonymous people who visit parks and poop on the floor of the freshly cleaned outhouses (The Phantom Shitter), people who make lovely little poo sculptures (The Shit Sculptor and Fecalangelo) and the person who stuffs the hand dryer vents full of poo (that person doesn't have a state-wide nickname).
