You are talking square miles.....not counties.
There may well be at least 1 hog in every county in AL.
But, you can well believe that people would never pay $600/night to hunt them if they could walk out there back door, go to their hunting club, or just ride down to their local WMA and shoot one!
That's a fact, Jack!

I know dang well I would not drive near as much, and far, as I do to hunt them. And, neither would you!
