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.
