Oklahoma on up to the Dakotas as well as the MidWest is often called "flyover country". The thought is people don't want to go there...and it's because of that you can see things many don't by travelling here.
There is, true, a "whole lot of nothing" in some areas - giving "wide open spaces" a whole new definition. Remember in some of the western states, because of this open area, it's known as "open range" area...meaning be on the lookout for cattle, horses and other animals in the road. If you hit you bought it, as the amount of territory makes fencing difficult at best and many ranches are so big it is up to visitors and motorists to be aware.
Oklahoma has been memorialized in many songs. Oklahoma City has a memorial site for the Oklahoma City bombing which happened the morning of April 19, 1995 - a museum and memorial pay tribute to those lost that morning, but don't capture the memories that never leave of thoe living in this area. In typical Oklahoma fashion, the city rose from the tragedy but the people have never forgotten the support of those near and far. The Cowboy Hall of Fame, horse racing and much more await as well as many activities that happen year round at the fairgrounds. Just west of the city is Yukon, a community that boasts being the home of world wide country entertainer Garth Brooks, although he actually lives in the northeast part of the state now.
Kansas and Nebraska both have many places to visit as well as further north into North and South Dakota, separate states with similar names. National points of interest such as Mount Rushmore, Crazy Horse monument, the Badlands and other points give a much different view of the US than people see on the coasts alone. In this center part of the country there are fewer celebrities and those that do live have not lost their roots.
