Oklahoma City

Oklahoma City needs 1 day: touring Frontier City, an Old West-themed park with roller coasters, and visiting the Oklahoma City National Memorial, dedicated to the 168 victims of the 1995 bombing of the federal building, the same afternoon. April-June and September-October bring the mildest weather, avoiding the peak of the May-June tornado season. It's inexpensive for a state capital. It was founded all at once in a single day in 1889, when the territory opened to settlement and tens of thousands of people claimed land within hours, a phenomenon known as the 'Land Run' that gave its residents the nickname 'Sooners'.
