I was surprised by the Chicago Museum Of Science and Industry. We have a MOSI here in Tampa Bay too, and quite frankly it is not very impressive, being mostly oriented towards kinetic displays for children. I was afraid that the Chicago MOSI would be the same way, but I had heard of the U-505 German submarine on display there, and figured that at least would be worth seeing.
And when I got there, I was pleasantly surprised. The aviation display was impressive, and the space technology display was equally fine. I had originally planned on visiting for just a few hours to see the submarine. Instead, I spent the whole day.
