Chicago - Day 2

On Tueaday, we got up early for breakfast and walked to Millennium Station to take the Metra to the Museum of Science and Industry.  We spent almost 6 hours at the museum.  The boys were the most interested in the U505 submarine.  It took us about 1.5 hours to walk through that exhibit because they watched every movie and ready almost every sign/display.  After the museum, we had dinner at Eataly before walking to Zoo Lights.
