Chicago's Moving Bridges II

My most popular photo on flickr, "Chicago's Moving Bridges over the Chicago River" is nearing 20,000 views and 200 favorites, so I thought I'd post another shot taken from that same day. This photo shows the same scene, but framed vertically and showing more of the sky and the Marina City corn cob towers.

I love how the river has a glass-like quality, and the fog that afternoon was certainly dramatic.
