The West Side climbs away from the river in short, steep blocks, and a hill like that turns four inches of snow into a real conversation with a car.

Salt goes where the grade and the shade conspire. Storms off Lake Michigan come through at all hours, which is why the plowing does too. A cleared, gritted drive on a hill is a small piece of engineering, and it feels like one.
