Established 42 years ago as a small town gas station just outside Walcott IOWA, 'IOWA 80' is now a giant of the US highways and the world's largest truck stop. Meet the people who live, work and visit IOWA 80. And visit the Annual Walcott Truckers Jamboree - the largest outdoor trucking event in the US. It offers everything from Pet Singing Contests to the Best Lit Truck at Night Competition. But at its centre is the Super Truck Beauty Contest. Hundreds of tonnes of gleaming metal thunders into the arena to compete for this coveted prize. It may look like a harmless bit of fun, but this title is taken very seriously. The Super Truckers are in it to win it, whatever the cost.
