September 4, 2013. I found out this morning that the Shedd Aquarium has been open until ten p.m. on Wednesdays since June. I then found out that tonight would be the last night. Of course I went, with a coworker and a friend, for Jazzin' at the Shedd. It was open until a decent hour for some of us, there was a bar, and there were jazz bands playing at three different spots throughout the aquarium. Also, there were no kids, so that was nice.
