I liked the shadow that was created by this eagle statue, by Frederick Cleveland Hibbard, in Grant Park. It looked like one of those cartoon scary monster shadows. I'll have to come back in the summer to take a picture of this statue when it is actually a fountain.
A side note: My sunrise picture from March 3 is on the NBC Channel 5 site in their weather slideshow "Proof That Spring is on its Way". Mine's the one with Navy Pier in it.
