David,
This group did sort of let you down, didn't it.
When I have been in KC, I have toured Mission Hills and KCCC, both near State Line Avenue SW of downtown.
For a really close one, RTJ's Tiffany Green is just south on I29.
Watson's course is on Highway 9 in Parkville, MO, near the airport, and worth a look.
Farther south, in Overland Park, etc. You have Nicklaus Lionsgate and a dozen others. Due south, you have Hurdzans Iron Horse in Leawood, Fazio's private course Hallbrook, which is one of his most difficult courses.
There is Tillies Swope Park SE of the city, but it has been changed. Even when I saw it years ago, it looked a lot like Dallas' Cedar Crest.
