We visited Chicago on Labor Day, and it was in some ways it was eerily empty. We did have a momentary crowded adventure on the "L", but overall it was a breeze to get around. What I love about Chicago is the amazing architecture, the river running smack dab through the middle of it, the wind, and the memory of my husband's marriage proposal. Chicago will always be a special city for us, we love going back because there is always so much more to discover. Next time, we are definitely doing a architectural kayaking tour -- doesn't that sound like a blast?
