I have never witnessed such a radically divided storm front as the one that confronted me on the shores of Lake Michigan on the evening of July 12, 2007. As I burrowed my tripod into the sand, I could not decide in which direction to photograph. To the north, the sky was black and a massive storm front was quickly approaching my location. To the south, the sky and water looked tropical and calm. I decided to be daring and wait about 30 seconds for the storm to literally get on top of me, and then I photographed straight west. The end result was a photographic version of a Taijitu, the traditional symbol representing the forces of yin and yang.
