Remember when you were a kid, and you used to play shadow tag? In this variation, you never actually had to touch another individual to say "you're it", you merely had to stomp on their shadow. Of course, this game is easier in the morning or evening when the shadows are longer, than at noon when it's probably easier to reach over and touch someone than to stomp underneath them with your feet.
Anyway, last Friday I was riding westbound on my two wheeled Beemer (affectionately known as Das Beak Zwei or DBZ) rather early to meet some folks for breakfast. In fact, the sun was just beginning to crest the seacoast horizon. As I rolled up and down the small hills of Rt 101, my shadow would appear and disappear in front of me. With the low angle of the sun, the shadow appeared huge at times, stretching out to 30 or 40 feet. Depending upon my direction, it might be on the right or left or out in front of me. Once, when it was on my left, I got passed by a car that drove over my shadow head. Made me think of shadow tag.
