For the architectural theme this week for flash of red month - this is the stadium where Chicago's basketball and hockey teams play. The large display (LED, I assume) is a new addition to the skyline. I'm wondering if there is a basketball game there tonight and thus the bb players, and if they'll change the display to hockey on the nights the Blackhawks play.
Amazing, it'll be very interesting to see what happens with the display. Wonderful image, of course. You live in such a perfect place for this part of the challenge.
I knew you would have interesting architectural shots this week!
