This is one of those impromptu shots that sort of jumped out at me when I wasn't really expecting to shoot pictures. I was driving north on the freeway out of the Denver area last year when the late-afternoon sky became interesting. Seeing this scene develop while being on a freeway with limited points to exit and stop, I was in a sort of photographer's agony. Time was of the essence, and I worried that the changing atmosphere would soon deny me the opportunity to create a great image. I eventually found this location that presented me with a reasonable view, composed the shot, and made my photograph. It probably wasn't the most dramatic presentation of the sky that evening, but I feel satisfied that I was able to capture the mood and place and share it with you.
