Honey and Papa came for a visit a couple weeks ago. Papa thought 10 days was going to be waaaaaaay too long to be here (staying in our house), but the time flew by and before I knew it they were headed back to Arizona. We fit in a lot of fun around Chicago, and lucked out by having beautiful weather before the heat and humidity arrived.
One day we took the train downtown and did the architecture tour on the Chicago River. Trains + Boats = lots of fun for 3 year old boys!
