Alton Brown and his crew are mounting their steely steeds once again and scouring the American landscape for honest road food. This time they will trace America's first superhighway: the Mississippi from the Gulf of Mexico to its Minnesota birthplace. The complete second season is available in a three disc set, with never before seen bonus footage: Each disc includes two segments from Alton's journey along the Mississippi River that never made it on the air, including his first breakfast on the road, a radio appearance, a visit to a New Orleans gelateria, and more.
