We stopped off at Home Depot in Christiansburg for some items Thursday and then headed over to the nearby Target store. I saw the sky as soon as I stepped out of the car. In photography, we call this a "wow moment," the brief instance when the setting sun provides the right touch of light and color to the sky. I had just enough time to grab my camera and crank off two shots before the sun dipped further below the horizon and the moment was gone.
