Oklahoma City

Lying in the Great Plains region, Oklahoma City has one of the world's largest livestock markets. Oil, natural gas, petroleum products and related industries are the largest sector of the local economy. The city is in the middle of an active oil field and oil derricks dot the capitol grounds. The federal government employs large numbers of workers at Tinker Air Force Base and the United States Department of Transportation's Mike Monroney Aeronautical Center (these two sites house several offices of the Federal Aviation Administration and the Transportation Department's Enterprise Service Center, respectively).
The city has been home to the Oklahoma City Thunder of the National Basketball Association since the 2008-09 season, where several notable players have played, including Russell Westbrook, Kevin Durant, James Harden, Paul George, and Carmelo Anthony. The team plays its home games at Chesapeake Energy Arena.
Oklahoma City is on the I-35 Corridor, which is one of the primary travel corridors south into neighboring Texas and Mexico and north towards Wichita and Kansas City. Located in the state's Frontier Country region, the city's northeast section lies in an ecological region known as the Cross Timbers. The city was founded during the Land Run of 1889, and grew to a population of over 10,000 within hours of its founding.

The city is bisected geographically and culturally by the North Canadian River, which basically divides North Oklahoma City and South Oklahoma City.
