Yup, it was Jeppesen, also my own HS stadium.
How neat that Jeppesen was your stadium. I remember old AFL games broadcast from there -- Curt Gowdy and Paul Christman -- Lou Rymkus was the coach -- George Blanda was the QB. In addition to Charlie Hennegan and Charlie Tolar, I remember Billy Cannon on those teams. In fact the Oilers won the very first AFL championship, beating the (then) Los Angeles Chargers.
