Can't tell you anything different then has already been said. If you decide pay to hunt, ask lots of questions to make sure that you know what you total cost are going to be. I have seen a lot of places that change extra, such as $1 per pound for a hog over 100 lbs, $50-100 per inch of cutter over a certain length.
I don't have a huge problem with paying the farmer something for hogs, either labor or a small amount of money, but the cost that I have been seeing recently are upwards of $200 a day, that just blows my mind.
