I do a waterfowl hunting trip to the area most years. Seen some really nice bucks on the NWR a few miles west of Clinton and I know some decent bucks have been killed farther west on Black Kettle. But there is a lot of barren open land out there too. Since it would be free plus cost of license for you I would think it worth it for you to drive out there one weekend now to at least look at it. Is your Father from there? I have old family roots from that whole area, Spradlins, Hardins, Musics, Marples.
