Zebra Stripes

When I am desperate for a blog photo, I usually head to the harbor.  I can usually find some kind of picture down there.  In this case, I was not disappointed.  I saw some swans swimming and put a long lens on the camera and started shooting.  What finally made the photo was when a boat went by and the wake, from some distance across the harbor, made these waves, which reflected the sky, or didn't, resulting in black and white stripes.
