Fog is mood, as well as weather. It is mysterious, lonely, melancholy. And depending on its severity, it can be a medium of abstraction in itself. This historic lighthouse, built in Cape Cod style in 1856, is now a museum and listed as private aid to navigation. I was fortunate to be able to see it and its lone cypress tree on a foggy morning. I caught the blink of its light through the morning fog, as well as a tiny figure that lends scale to the image.
