I checked out Lexington WMA which is about a 45 min drive from OKC this weekend and there are hogs out there but I didn't see any alive lol. There was 1 dead on the side of the road. (300 lb sow) There are several creeks that go through the area and several green fields planted by the wildlife department. Ya might be able to talk to the local warden and he will probably tell you exactly where to go as they want the hogs gone.
