Actor Bradley Walsh and his 20-year-old son Barney hit the road together, travelling more than 2,000 miles from Los Angeles to New Orleans. In the second leg of their journey, the pair leave the city of Los Angeles behind and make their way down the famous Route 66 to the southwestern state of Arizona. Here, they ride through a deserted ghost town, before the father and son reach Lake Havasu City, where Barney has arranged for them to try jet-skiing. Finally, they attend a Cowboy College, where they learn to become real-life horsemen.

The actor and his son Barney arrive in Texas, where they enjoy driving around in tanks, experience space travel in a centrifuge and hear campfire tales about UFOs. First up, the pair undertake some centrifuge training, which is used to prepare astronauts for the crushing gravitational forces produced at take-off from the extreme exhilaration. They also head to the outskirts of Houston to meet some UFO enthusiasts who investigate claimed sightings of extra-terrestrials and are gripped by stories of spaceships blocking roads and people being taken by aliens for experiments.

In episode four, Bradley and Barney travel to New Orleans in Louisiana, the fourth and final US State of their trip. Sitting on the mighty Mississippi, New Orleans is known for its vibrant nightlife, live music and laidback attitude. Bradley and Barney drive across the border in their RV and head straight for the city’s most famous mode of transport – the steamboat.
