Check the Oklahoma Predator Hunters Association website. They have an Ask the Warden forum and this has been discussed thoroughly. Basics are you have to have a written permit from the county game warden that is only good for one 24 hour period (noon to noon). Some wardens give permits freely and some don't give any at all. You can also access the hunting regs online at the Oklahoma Wildlife Dept. website. Hope this gets you going in the right direction. Good luck.
