Philadelphia Long Exposure

I revisited this shot in my Lightroom collection. For some reason, I had the vibrancy jacked up really high. I undid that somewhat. A cab drove in front the camera while I had the shutter open. I thought it added an interesting element to the shot. I think I might have had the shutter open for a stop too long. The Comcast Center and the building it to its right are out of focus...Oh well. This was the first time I shot a city at night. So I was learning as I went.
