BY RICHARD MIZE, Real Estate EditorTown and gown have come together with shovels and hardhats for several combo education-event centers in Oklahoma’s regional university towns. It has added up to tens of millions of dollars in development — and new venues and civic pride — that neither the cities, local businesses nor the universities could afford on their own, said Susan Winchester, chairwoman of the Board of Regents of the Regional University System of Oklahoma. Projects of note are: Pioneer Cellular Event Center, a $24 million patnership between Southwestern Oklahoma State University and the city of Weatherford. Northeastern State University Event Center, a $17.1 million partnership between Northeastern State University and the city of Tahlequah. Harland Stonecipher School of Business and Chickasaw Business and Conference Center, a $14 million partnership between East Central University in Ada, the Stonecipher family, which founded Ada-based Preqaid Legal Services, and the Chickasaw Nation. CHK/Central Boathouse, a $6.8 million partership between the University of Central Oklahoma and Oklahoma City in the Boathouse District along the Oklahoma River. Lesley L.
