A shoe without its mate is a forlorn thing, especially if it’s somewhere out of place, like on the side of a road or, like yesterday, in the muddy shallows of a river. Where is the other shoe and, more importantly, where is its owner? I could concoct a million stories about how this lovely black flat found itself in the Monocacy, but there is only one true one, and I almost certainly will never know it. Still, I like the possibilities.
