I had an hour before I left Chicago so I stopped for a short visit. I wish I had more time to explore! The exhibits were super fun and I found myself wanting to spend a lot of time reading the history and information of all the memorials. The most interesting thing I learned was that the name Chicago came from, and they had a really cool old-fashioned subway car that you could sit in. My only complaint (although I don’t feel there will be a real solution) was that the tour group being led was so loud that I was distracted while I was trying to explore alone. Overall worth a visit!
