Before there ever was Chicago Metropolitan Airport (present-day Midway) and O’Hare Field, before jet planes and roller-board carry-on, Union Station was the official entrance to the Second City. This sign has pointed the way for generations of Americans.

Imagine the clip clop of visitors toting their heavy coats and trunks through a cavernous marble lobby lined in polished brass trimming on the way through the vastness of middle America.

And here I am, like millions before me, beginning my journey from these halls, these rails.
