As I was out today for Day 13 of Thirty Days 2011, I was near the corner of Speer and Champa in the late afternoon take some pictures when a driver in a car at the red light started talking to me while he was waiting for the light to change. He mentioned the reflection of the city on the building a block back from the direction he was driving. As soon as he mentioned that I thought about it for a minute and knew what building he was talking about as I had noticed that scene before. I was heading back in that direction to my car and stopped at the building to photograph the reflections and skyline of Denver. Just as I was heading back to my car, I noticed a smaller area of glass and used this reflection to create the image for Day 13.
