Ken Burns- The Dust Bowl -Blu-ray-

The Dust Bowl chronicles the worst man-made ecological disaster in American history, when a frenzied wheat boom on the southern Plains, followed by a decade-long drought during the 1930s, nearly swept away the breadbasket of the nation. Menacing black blizzards killed farmers crops and livestock, threatened the lives of their children, and forced thousands of desperate families to pick up and move somewhere else.
