Would like to say just how beautiful it looks  So clean and crisp, Not too hot this week as I heard last week was  really steamy(Pun Intended)-   It is kind of quiet though, not what I expected.  Any suggestions for places to see while I'm here?

Museums? Art Institute or MCA are fun.

The Art Institute is great, Shedd Aquarium is good if your into that.
Take one of the boat tours on the river (architecture one is interesting)
95th  restaurant/bar in the Hancock building has great views
Navy Pier (boat tours, ferris wheel & other things)

All of these are right downtown
