Chicago is a rough place. Especially that Cabrini Green area. I went to Corian school in Chicago and when I first got there I pulled off the Interstate to gas up. A black man walked up to me and said, if you know what's good for you , you'll get back in that truck and head north outa here. I guess my Missouri tags and my complexion made me a target for some reason.
