Even if you have no plans of entering the Planetarium, go to Adlers when you are in Chicago! It was so fun to see the city from that angle. There was plenty of (paid) street parking the times I went there.
My kid absolutely refused to believe that Lake Michigan is a lake. Back in Denmark, we can look across the ocean to Sweden, so how can this endless span of water be a lake??
I guess I like contrasts. In the summer I post Christmas lights and in the dark of winter (and it is indeed dark and dreary where I am) I post green trees.
The Adler Planetarium happens to lie on the banks of Lake Michigan, a beautiful space.
My first visit there was just to check out the parking facilities. Second time I brought my camera.
