I was lucky to get that photo. It was during my time in the Navy, and I was attending a school in San Francisco at the time. So my wife and children came up at the end of the week for a short visit to the Bay Area. We had just arrived at the Muir Woods park when a movie crew set off some smoke bombs to accentuate a scene that they were shooting, and so I took advantage of it myself. That remains one of the favorite pictures that I've taken.
