Overton County definitely has issues, as do others. It is still illegal to take shots on other people's property without permission. I would assume scanning would not be illegal, just like looking in the daylight with your eyes isn't. OC has the rich guy that raises wild hogs to turn out or sell, TWRA is well aware but does nothing about it. Money seems to matter more than the spread of hogs in the area. It's literally a big enough operation that you can see it on aerial imagery but yet nothing is done.
