We look up, if only to see if we're likely to be rained on. The sky calls attention to itself, whether scored by herons, cranes, or wires; illumined by sunsets, Perseids, or ballparks; broken up by the twigwork of oaks or maples, painted in rainbows, or just primed in the pale gray of my '52 Ford. If we are truthful, the sky is never neutral.
