You can spotlight for them with game warden approval and they seem pretty free about it if you are the property owner or lease holder. Hogs do a lot of damage. That fellow is a hog killing machine. I'd hate to have to load 9 hogs....much less process them.
We have a guy that I work with on occasion that has land around witchita Falls Tx. He has pics of lots of pigs he has killed. He just leaves them lay.
As one doesn't have to have a license to shoot them, I tried to get him to let me come down, and help him, but found out later the only people he lets hunt on him are the corporate big wigs. You can figure out what his nickname is.
