14 Route 66 Attractions to See on Your Next Road Trip

There's a 76-foot-tall oil worker sculpture, known as the Golden Driller, standing outside Tulsa Expo Center (4145 E. 21st St.). The center is said to contain the world's largest unobstructed interior volume. The roof is suspended by a system of booms and cables, which allows adequate room inside for over-sized equipment shows. In fact, the original Golden Driller (he was upgraded in the 1970s) was put on display inside the building for a while prior to his outdoor placement in 1966.
