Not all of use landowners charge but we do like to really know someone before you come on our land. Usually that means a friend. The places that charge also charge for deer, dove, quail and what ever else for them its an income with little input. Some of those places buy cut boars to put on there place and then charge a fella to come and kill a 500lb hog. Hogs that big don't have any family jewels. As for my place it doesn't hold hogs just come ever so often and root up a field.
