It's the famous King St. at Old Town Alexandria. Despite the rain, it was still buzzing with life. And those festive Christmas lights are a year-round thing. It's a great place for a walk at night (if you don't mind the occasional young professional waltzing around in his/her drunken stupor).
I used a tripod. The camera was around 1.5 feet off the ground. The tricky part was timing. If the traffic light changed in the middle of the shot, it created a bizarre sequence of red, yellow, and green traffic lights (as if the traffic lights were malfunctioning and all three lights were on). I tested out few aperture settings to conjure up the right amount of exposure.
