We saw on the news last week before we left that there was a little “issue” with the sky deck at the Sears Tower (or whatever they call it nowadays) in Chicago. Seems the plexiglass cracked under the weight of a few daredevil viewers. It reminded us of this visit in 2012 to the Palazzo Vecchio in Florence, Italy, where you can stand over the holes once used to drop nasty things (like boiling hot oil) on attackers and miscreants hundreds of feet below. It’s a great way to quell political dissent.
