Weather and circumstance seemed to be conspiring against me. The entire morning had passed, and I had no photos to show for it. Then I wandered into an area I typically avoid. Suddenly, the sun came out. Then the signal near by changed to an approach. Quickly, I stopped near the fence along the right of way, and jumped on top of my F-150 camera platform. Moments later, this Z train rounded the corner with fine Warbonnet out front. Like I said, Serendipity!
