There is a corner of the Upper Midwest that does not look like the rest of it. Where southern Wisconsin, northeast Iowa, and southeast Minnesota meet, the land rises into steep wooded bluffs and narrow valleys, cut by cold streams and dotted with small farms. It is called the Driftless Area, named for what it lacks: the glaciers that flattened everything around it never reached here, so the old, folded landscape survived. For a slow weekend, it is one of my favorite places to point a car.
