The city state of Chicago is about 300 miles from Wood River.
Wood River is across the Mississippi River from St. Louis
I understand the physical geography, but I was refering to the political geography. I referenced the classical "city-state" form of sovereignty where the political control of the city extends into the surrounding hinterlands. If one were to draw a circle with a radius of, say, 45 miles centered on the Sears Tower you would find that it encompassed all or part of at least 50% of the House AND Senate districts. Thus, while some may call it the State of Illinois, given the influence of the Daley family those outside that circle can equally refer to it as the City-State of Chicago.
