Organized by Ples and Margaret Harper in 1960 for the purpose of producing and financing a summer outdoor drama in the new Pioneer Amphitheater in Palo Duro Canyon State Park. Paul Green, the famous outdoor dramatist, was commissioned by the Harpers to write an outdoor play. The result was "Texas", now produced annually during the summer months. Margaret Harper and the Texas Panhandle Heritage Foundation also produced other plays, "Thundering Sounds of the West" and "They Came From Spain" in 1965 and 1971, respectively.
