Hey, you were close! It's the Mike Monroney Aeronautical Center on the west side of Will Rogers World Airport. The Guard base is in the SW corner, next to the Metro Tech (A&P school). Where I live is just a few miles north of there. OKC streets (well, most of Oklahoma!) are set up in a grid system, with major streets one mile apart (they follow the section lines on a topo chart). Makes it easy to get around and find things.
