Steve Goodman was a Chicago folk singer/writer in the 70's - 80's.
He wrote the song quoted to poke fun at the Chicago "City People" that thought civilization ended at the Chicago city limits and had never been out of the city.
As a "Downstate" person myself, I have always chuckled at the Chicagoans I have met, that know nothing about our Illinois communities yet all of us Downstaters know everything about Chicago.
Good Luck with SIU and being a mother!
When I was an SIU student, I couldn't understand how the married students managed to be a student and a spouse at the same time. To be a parent and a dental student was far, far out of my understanding.
I wish you well.
PS Check out the Amtrak Train Schedule!
In non-COVID times there are 3 or 4 trains a day between Chicago and Alton and the times are not to bad.
