Casting a Shadow

I spotted this guy the other day around Heisler Park. There was something about this moment that seemed so familiar. Then I realized... this guy was the inventor of the 'Duck Shadow' we have all seen in lecture halls.

He was in the process of casting a "double shadow' on to the ocean. A double shadow is about as difficult as a 'Quad' in figure skating. I was so nervous for him. .. I can't look when the pressure is on.... and the participant can slip.

Actually.... he only ended up casting a single Duck Shadow.... the tree blocked the 2nd Duck.
