With an estimated total population of about 3.5 million people, Oklahoma is the 28th state in population.  2006/'07 marks the centennial celebration of the statehood of Oklahoma with many events scheduled across the state. Many people in the world associate Oklahoma City with a terriorist act, while others think of the state as the desolate and windswept depression-era landscape described in Steinbeck's The Grapes of Wrath.  While the former is aware of it's past and celebrates the human sprit discovered from the tragic events of April 19, 1995, the latter is far from true now.
