I headed out to photograph the Board of Trade at the end of LaSalle, but the photograph failed.  Too much light pollution from the traffic jam at rush hour.  I needed to get the cars blurred, which required a longer exposure, but that meant that the Board of Trade was overexposed.  I need to comeback on a Sunday.

Meanwhile, as I was standing on the traffic island, I looked to my right, seeing the lovely blue sky.
