County Line

I've been listening to an album entitled "Field Recordings from the Cook County Water Table" by Brokeback. It's a cool recording, but that's not why I'm mentioning it. It just dawned on my that the first county that was able to identify, with the exception of the county where I grew up, was Cook County. I'm pretty sure that I learned where Cook Country was located (in Illinois, encompassing all of the city of Chicago and some outlying areas, in case anyone wasn't aware) from an episode of Punky Brewster, but I'm not entirely sure. I seem to remember an episode where Punky had to go to the hospital. Before cutting to a shot of Punky in her hospital bed, they showed some stock footage of a hospital in Chicago that had Cook County somewhere in its name. I don't have any other interesting stories for how I came to learn the names of any other counties. By the time The O.C. began its run, I already knew where Orange County, CA was. Of course, I've never actually watched the show, so it wouldn't have helped me anyway.
