Chicago wouldn’t exist without water. The only reason we’re all living here now is because this former swamp helped connect the Great Lakes to the Mississippi River back in olden times. And when Chicago was built, old-timey Chicagoans literally lifted the whole downtown up 8 by feet so its buildings could sit above the flow of the water.
A feat of engineering, just like when slightly less old-timey Chicagoans reversed the flow of the Chicago River away from Lake Michigan instead of into it. Heck, the blue on our city’s flag represents water. So yeah, we’d say water and us go way back.
