Note: The USA's classic byway, Historic Route 66, stretches 644 kilometers across Oklahoma. There's no better way to explore it than renting a car and driving it. On the road, you'll encounter retro car service stations, museums, the State Capitol building and landmarks like the Round Barn — now restored to its 1890s grandeur.

Note: Stop at roadside attractions like the world's largest bottle of pop, found outside Pops Arcadia. Pops serves up nearly 700 varieties of soda ranging from classic colas to unique flavors like peanut butter and jelly. Pair your choice with classic U.S. diner fare like hamburgers, fries and milkshakes.

Note: Take the Interstate 44 interchange and follow signs to the National Cowboy & Western Heritage Museum—the place to learn about the USA's Wild West roots. Visitors have been coming to this unique museum for more than 60 years to see art and artifacts preserved from the U.S. West and to learn about the history and cultures of this time. View sculptures and paintings by renowned United States' artists and a full-size replica of a Western town or browse galleries on firearms, rodeos and cowboys. Outside, a beautiful garden and children's area delights the young and old.
