The Hairy Bikers (Si King and Dave Myers) embark on their most iconic road trip to date – America's Route 66, to celebrate the food, history and culture that lies within this rich, rustic part of US. The boys motor through nine different states, carved into six legs, spanning over two thousand miles in which they visit destinations like Chicago, St Louis and Las Vegas, and travel through incredible landscapes from vast prairies in Oklahoma to the staggering scale of the Grand Canyon.
