Welcome to Oklahoma.
Check out www.wildlifedepartment.com
That is the Oklahoma Wildlife Department web page. Look at the interactive map for WMAs. That will give you some places to scout. Be sure to read the hunting regulations (available online there also) closely to see what is legal on the WMAs. Most are open for archery, but not all are open for black powder or rifle.
Ft Cobb has been a hot spot in the past (for ducks and deer). But there is a lot of pressure there also.
Lexington WMA is supposed to have some good deer hunting.
Black Kettle and Packsaddle are supposed to be pretty good also.
Hackberry Flats is managed for waterfowl, but there is not much water there right now.
Mountain Park WMA typically has ducks and bucks.
