A few nice Colorado Airport images I found:

All things come to an end. This photograph was taken whilst we were sitting in the plane waiting to push back and begin the flights back home. I was looking out across the tarmac towards the other aircraft and the setting Sun, thinking back over the events that had made this such a wonderful and productive trip. All that remained was the series of flights back home : Denver – Los Angeles – Sydney – Canberra. Although the total transit time for this combination of flights is a little over 24 hours, it all went smoothly with a minimum of discomfort – which is as good as the travel experience gets these days.

The window through which this photograph was taken was scratched and frosted, and this imparted a texture on the photograph. The image was further degraded by the usual number of reflections artifacts. Given this situation, I decided to go with the textured look. My app-of-choice for this is Painteresque – others use ShockMyPic or Tangled FX to obtain similar textures.

Denver International Airport, Dec, 3, 2006, after the solstice blizzard. As I waited for 2+ hours in the security line, I saw outside the windown someone drew in the snowfield outside, "I [heart] DIA."
