Driving into Chi-town on 55, looking at each side of the road, that's about what I'd expect. Just like Tulsa, there are some areas virtually crime-free, others resemble war zones.
I really think there's a common denominator, but I just can't quite figure it out.
In any case, if you find yourself in Chicago go to Chinatown....Joy Yee Noodle. I once drove up there just to eat.
