RE: Hog Hunting on Public Land
I've spent lots of time on several WMA's in oklahoma and there are a few that have decent hog populations. I've been hunting Lexington for a few years now and I don't think there are pigs on it... I've never seen a track one.
Canton WMA, Three Rivers, Black Kettle, Cherokee, and most of the areas in SW oklahoma have pigs. I would personally go to either Canton and hunt on the Canadian river, or I would go to Black Kettle on the Texas border.
There aren't as many hogs here yet, but they have had a huge explosion here in the last couple of years and are steadily making their way throughout the state. Most landowners are more than happy to let you kill pigs on their property.
