I live in NW Missouri and spent the better part of several days trying to call and research places to hunt hogs that were within driving distance. The conclusion I came to was it was either Shiloh Ranch around Ada, OK or you really need to head on to TX.
I've had great luck with an outfitter in NE Texas. stretchastring.com. James Fosters place really isn't that much further than OK. Your going to spend 10 hours at least driving to southern OK and so about another 3 hours and your at stretch a string.
Personally I'm really leary of one of those places that is mostly a gun hunting only type hog hunting facility.
Hope that helps,
Chris
