If the world makes any sense, Garrison Keillor has made this joke already. The one about what happens when you leave a man too long in the midwestern outdoors, armed with nothing but a heap of refuse and a barn full of tools. What he does is, he makes a sort of monument to . . . it’s not clear what, exactly. But the fruits of whatever passion inspires him grow in the region’s out-of-the-way passages, appearing roadside in Wisconsin and Michigan and elsewhere. It’s bold, eye-catching art—open-air, weather-ready, and not unimpressive in size—but it’s probably too whimsical to be the product of pure male ego. Not for the midwest man some bland phallic stand-in.
