In May of 2007, I happened to be at the top of the Key Bridge Marriott Hotel in Arlington, VA. That hotel has the most amazing view of DC and Arlington from its ballroom, which sits right on top of it and has floor to ceiling windows.
I also just happened to have a video camera and tripod with me (ahem), and took some footage of the DC skyline, the Key Bridge, and the Potomac River. That footage sat around on my computer till last week, when I finally had the time to edit it properly and to work on a soundtrack for the video.

By the way, I took this photo that same evening, from the roof of the building. The hospitality manager was a really nice guy and he let me go up and spend about 15 minutes taking photos up there.
