One of those unusual things you see on the side of the road when driving around America is the Golden Driller of Tulsa, Oklahoma. At 23 metres / 76 foot it is one of the largest statues in America. It was built in 1953 for the International Petroleum Exposition and was used again in 1959. The Golden Driller was so popular it was set up as a more permanent structure at the Tulsa Expo Centre for the 1966 exposition and that is where it has remained ever since. In 1979 it also became the state monument.
Not far away on the Historic Route 66 is another old roadside attraction. The Blue Whale of Catoosa, Oklahoma. It was built in 1972 as an anniversary gift on a small pond but became a water slide/swimming hole attraction. It eventually closed in 1988, but was restored in 1997 an remains an attraction of sorts today.
