Yes, I skipped a day. And, yes, my mother called me to ask about it.  Thanks, Mom--I know you'll keep me on track.  So, here it is: my attempt at a night-time shot.  A rather sloppy attempt.  I'm going to come back to this another time and see what else I can do.  If you have any suggestions of pictures I ought to be taking here in Chicago, let me know, and I'll try to get them for you!
