Kentucky Derby Day and my grandfather's birthday (1885). I had to run into Torrington and had to stop by my favorite glass cube building, the Torrington Office Plaza on East Main St. The clouds had been spectacular all afternoon, but by the time I got there, the sky had gone white overhead, leaving blue only to the north. So I got the north side of the building with reflected blue (and a little Photoshopping to saturate it a bit).
It counts (as "doors and windows") if the entire building is windows, doesn't it?
