In the spring, here in Chicago, we sometimes are blessed at dusk with the most brilliant, perfect, deep blue skies. The lights of the city look like a carnival against that blue, or a fire, or candy. The colors play tricks with your eyes – with your depth perception, your sense of distance. The air is charged and heavy and utterly beautiful. We had one just the other night. See?
