Old Main Branch
Production on part of the new Transformers (3) movie wrapped at the old Chicago Main Post Office, in the West Loop.
This gorgeous, gargantuan structure (which has been vacant for years) is literally across the street from my office building. I walked across the street with my DSLR on my lunch break, and took all of ten minutes to get a few shots.
As an amateur photographer, I feel so blessed to live in Chicago.
