Guy Fieri has his friends and family in tow as they finish up their epic Appalachian adventure through Tennessee and Kentucky. Along the way, they're eatin' gourmet mushrooms and Southern sweets, touring a cast-iron cookware factory and visiting an aquarium where they learn how to cook for lemurs. Plus, the families make custom hats, battle it out in wild competitions and go whole hog in a celebration to wrap up an awesome road trip.
