Billy Connolly's Route 66

Billy sets off on his motor-trike to fulfil a lifelong dream of travelling along the world's most famous highway. Beginning in Chicago, he goes to the top of the Willis Tower, America's tallest building, before visiting the home of Abraham Lincoln in Illinois and meeting the state's champion pie-maker. Going off-route, Billy heads to Amish country, where he takes a horse-drawn buggy ride, and then talks to two women in St Louis whose homes were recently destroyed by a tornado.

Billy begins this second leg of his journey in St Louis, Missouri, by climbing the Gateway Arch - which signifies the start of the American West. He visits a wolf sanctuary, takes in a Civil War re-enactment, tries his hand at hunting wild turkeys and makes himself comfortable in the world's largest rocking chair. His final stop is in Oklahoma City, where he visits a memorial to the 168 victims of the bombing of the Alfred P Murrah Federal Building in 1995.

Billy joins ranch hands on a cattle drive to Oklahoma City before heading into Texas, where he visits the ghost town of Glenrio and Devil's Rope Museum. In Los Alamos, New Mexico, he meets two men who helped create the atomic bomb and attends a rodeo in Arizona. Driving off-route, Billy ends the episode in Monument Valley, where he talks to a Navajo medicine man.

Billy completes the last leg of his motor-trike journey along the world-famous Route 66. He 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. Last in the series.
