Billy Connolly's Route 66

The comedian completes the last leg of his motor-trike journey along the world-famous Route 66. Billy visits a massive meteorite crater in Arizona, before heading to the Grand Canyon. He meets a campaigner trying to keep the historic route alive, and bottle-feeds a lion cub in a sanctuary for unwanted exotic pets. Finally he reflects on his 3,000-mile ride when he ends his travels in Santa Monica, California.
