America's story is one of migration and expansion. In this hour, we explore the history of America's highways and byways. We hear from Gridlock Sam, who fights traffic for a living, and Peter Norton, who takes us back to the dawn of the motor age. Then we travel through America's canalways with batteau reenactors and John Larson, a scholar who explains the delicate issue of who foots the bill for internal improvements. Finally, Susan Rugh reminds us that "freedom of the road" simply wasn’t a reality for black Americans in the 1950s, a period when physical and social mobility seem particularly linked.
