What all these films capture can still be experienced today. Just past Chicago, in Wilmington, Illinois, stands the Gemini Giant, a fibreglass astronaut about nine metres tall, complete with a rocket. To the west of Amarillo, ten Cadillacs are stuck upside down in the ground at the Cadillac Ranch. In Adrian, Texas, the Midpoint Café marks the halfway point of the journey: it is 1,139 miles – just over 1,830 kilometres – from here to both Chicago and Santa Monica. Next come the Blue Swallow Motel in Tucumcari, New Mexico, the Wigwam Motel in Holbrook, Arizona, and the Bagdad Café in the Mojave Desert. And right at the very end, on the Santa Monica Pier, stands the ‘End of the Trail’ sign, perfect for a souvenir photo. On the way there, travellers experience what McCartney loves so much about the M6: watching the landscape change. On Route 66, this journey takes you from the fields of the Midwest, across the vast plains of Oklahoma and the Texas Panhandle, into the deserts of Arizona and California, and finally to the Pacific Ocean. Thrills? They’ve been standard fare since at least 1946.
