Plumbing

I was wandering along this dingy alley ... (I seem to spend a lot of time in dingy alleys. The muggers are beginning to talk) .... when I came across this especially disreputable piece of plumbing. I'd rather not consider what goes down it and what (given the missing cap) now comes OUT of it but it matches my penchant for all things grunge and earns selection for today's outing.
