Nah, you're wrong Dr Bill! This old house featured a shotgun house in New Orlean's a few years ago, so many PBS veiwers know them..

of course, in the north, in tenements, the same layout was called a 'railroad' flat, and old ones were very un appealing. (since many of the windows only opened onto chimney like air shafts.)
one of my fathers older cousins lived in one, complete with a soapstone sink, made into a double sink with a divider, and you took the divider out to make a bath tub! it was a low sink for washing, but high for a tub, generally the worst of both!
