Host Ira Glass talks with a guy who hit the road after his mother's death, hoping for some experience that would change him and shed light on what just happened. This never happens to him, or to most of us.

Ira with "The Hens," a group of nine middle-aged women who've known each other since girlhood. They play recordings of their recent three-day road trip from Chicago to a casino in a cotton field in Mississippi.

Ira teaches Sarah Vowell how to drive with some advice from Tom and Ray Maggliozi, the hosts of NPR's Car Talk. It turns out that although we think of how-to's as the most rational thing in the world — follow the simple instructions and you'll learn — in real life, they're anything but simple.
