Out on a ledge in Chicago!

Had a great time in Chicago celebrating Alex's 13th birthday (which was actually July 16th). We went to the Museum of Science and Industry, and to the Sky Deck at the Willis Tower. All in one day!

I still can't believe I went out on the ledge. 

The Sky Deck is amazing!  The cube of glass - 4 of them - stick out the side of the building on the 103rd floor.  Standing in it allows you to see straight down, as well as to the sides.  Simply remarkable technology.
