If you play Milburn, there is little Langford left that is visible. Either Packard or Gill remodeled it years ago. I have played all the other ones except for Wolf Creek and Lions Gate and all are nice tests.
There is also KC National by Watson which I have also played. I don't even know how private it is, since I played as a guest. Worth seeing, although it runs through housing.
Right near the airport is RTJ II Tiffany Green, which I have also played. Pretty standard RTJII stuff, but the fifth green is an interesting center depression green, which I loved and the pro shop apologized for.
Now, if you want to drive a few hours, you could go to Manhattan and play Colbert Hills, which has better topography, etc. But, it sounds like its out of your time frame.
