I've Been Out Picking Coal

Well, not really. However, I was in a portion of this country that best known for coal, that being the Coal Region of Pennsylvania (Shamokin, Mount Carmel, etc.). And one thing I can tell about this area is that it's a lot different than it is here in Mount Vernon, Missouri. One such thing that stands out is that most of the houses up there in PA are duplexes (or, as they call them, "doubles". If you live in one side of one of those duplexes, like my aunt Linda, who lives in Shamokin, you are said to own "half a double". Also, most of these duplexes have a third door below the other two, presumably for coal storage.
