This is what I consider to be the first good photo that I ever took.
It was shot back in 2011, when I was backpacking around the United States with my first dSLR camera in my early 20's. I had woken up one morning to do some landscape photography and was still shooting a couple of hours after sunrise, when all of a sudden I looked over my shoulder and saw this cowboy about to ride into the shot. It was one of those beautiful moments that you can never plan for that often make for the most interesting photographs.
