Drummond Flats is also public access southwest of Enid in Garfield county, and my son has hunted quail there and seen some really big bucks.
I own a small place in Alfalfa county, and in the 14 years I've hunted up there, it seems lease places get harder to find (for whatever reason). The place I first hunted on was in Woods county north of Alva on the state line, and we never killed anything big there. My brother did see a giant walking out one evening though. I live in Texas but have quit deer hunting here. NW OK has spoiled me.
Here is my 2014 and 2015 bucks.
Good Luck with your search.
