My wife and I were once harassed by two Chicago Police officers when we
approached the Meigs Field terminal several years ago... this was in the
late 1990s, after the police had "confiscated" the second floor of the
terminal to use as office space.

It was the "station" for lakefront police patrols.

We were asked about our business at
the airport, to which we responded that we were pilots who had never
been to Meigs and wanted to look inside the terminal. At that point, we
were promptly told to leave the property because the airport "isn't open
to the public." We came back later, when we encountered no police and
were able to enter the terminal and observation deck. We all know how
that book eventually ended.

Yeah, rock and roll! And the terminal itself houses injured birds.
