Central and North Chicago
Looking North from the 103rd floor (SkyDeck) of the Willis (aka Sears) Tower. The other tall building in the distance (with the dual antennas) is the Hancock Building - where they also have a great view from their observatory. If you see the evening shots of Chicago in my Photostream, they were taken from there. If the clouds look a little 'off' that's probably some of the grime on the windows that I couldn't shake.
