Another gray day in Chicago

It's a perfect museum day; cloudy, humid, damp. That said, I didn't actually go inside the Museum of Science & Industry. It is, after all, a workday! But the building has always been a favorite of mine. It was originally the Palace of Fine Arts at the World's Columbian exposition of 1893. If you haven't read The Devil in the White City by Erik Larson you should; it's a masterful telling of Chicago's triumphant battle to host the World's Fair, the architect Daniel Burnham's heroic struggle to build the fair and H.H. Holmes' awful use of the fair as a source of victims in his killing spree. I wonder if Mr. Holmes visited the Palace of Fine Arts during the fair and we now follow in his footsteps when we visit the Boeing 757 or the German U-505....
