I remembered walking past a kids' play area at Chicago O'Hare a few months ago, so I asked information where it was. Thought it would get the kids off my back for 15 or 20 minutes. Instead, the play area turned out be a branch of the Chicago Children's museum and the play equipment, though simple, was innovative and laid out very well. The children happily spent nearly three hours in the play area.
To the Chicago Children's Museum and Chicago Mayor Daley, a heartfelt thank you.
