Yeah, well I remember the equivalent of the rag and bone guy, IP. I'm 91 years old, and I remember riding with the milkman sometimes in the morning before I was in kindergarten. His wagon was hauled by a single horse, as was your rag and bone enterprise. For a real picture of what was underfoot, check cities like NYC or London when transportation was by horse. Fortunately, horses don't eat meat, so the stink wasn't as bad as it could have been.
