Thanks! I appreciate all of the votes and feel honored to have been included with the other entries as they are all terrific shots.
Nothing too special about that shot, though. It was about 8pm and I was just doing one of my nightly tripod excursions around the park and saw a clearing of people in front of the Astro Orbiter (soon to be gone perhaps). I had the Sigma 10-20mm on my D300 and plopped it down to wait for the ride to start moving before firing the remote cable release. Below is the EXIF.
