On a photowalk with Taffy and Meg, we took the Chicago Architectural Foundation's tour of The Rookery.
PS
I just saw Taffy's post, and hers is SPECTACULAR! We were standing right next to each other, and she had commented that my photos were upside down from hers but her photo composition and processing are really fabulous. Take a look for yourself: http://365project.org/taffy/365/2015-10-22
