I lived in Oklahoma City a few years ago and loved it!
We were in Edmond which is North of the City and Tinker is East. Depending on how far you're willing to go from the base, Edmond has excellent schools. Oklahoma City public schools are not the best but if I remember correctly, Midwest and Del City's schools are okay.
If you'll be in need of childcare, Oklahoma State University's Oklahoma City Campus (near the fairgrounds) has a FANTASTIC child development center. I worked there for two years and wish we were still in the area so I could take my daughters there.
If you have any more specific questions, please feel free to get in touch with me.
