We visited the Art Institute of Chicago, The Bean, the Aquarium, Eataly, Navy Pier, and did the river architectural tour which I would highly recommend. Ben took us to an amazing Thai restaurant and Jenny's Icecreams (the best and maybe the most expensive ice cream I've ever had). And in case you can't tell from the photos, we were freezing the whole time. 40 degrees in Chicago is very different from 40 degrees in Utah.
We also visited Harry and Sarah who live near Detroit. Harry works for Ford so we went to the Ford Museum which was HUGE. I'm really proud of us for making it through an entire Tiger's Game considering how cold it was. We had so much fun seeing these two.
