Our family was planning a trip to Chicago and this was part of the "City Pass." Looked fun, we love museums, so decided to add it to our itinerary. It was a very good museum, almost too much "stuff." Whatever your interest, there could be a whole display of whatever that interest is. It was a bit too "static" for my 16 year old son. He enjoyed it, but I think at times was a bit like "how many skeletons can we see?" But there were a lot of interesting displays. When we visited there were large sections covered in brown paper due to something with indigenous people. While I get that, and respect that, seems like they could have taken those items out of the displays for the time being, and closed off a room or something (or displayed something else in their place).
I was a tiny bit disappointed as this museum could have been anywhere in the country. I guess I should have expected that, but didn't see much that was directly "Illinois" related. It is still a very good museum, and will probably be on our "to do again" list if we return to Chicago someday.
