If song lyrics count, Eleni Mandell's "Iowa City" is the poem that will always stick in my mind about that town.
Girls, the boys don't cheat in Iowa City
Iowa City nothing to do
Now they're crisp and they're clean
Iowa City
Iowa Iowa
Skies are blue
Not so, Chicago
Never, New York
When you're off and you're looking for something
What will you do?
Where will you go?
