Well for those that don't have hogs on our land I would pay. If you provided lodging (depending upon the quality???) then I could see paying $250-$300 for a two day hunt. Also, I would want to hunt over a feeder in a stand and have a good shot of seeing something. If you are thinking of opening up something like this, I would let 8-9 guys hunt it for free in exchange they give you testimonials and show pics of thehogs they killed off your land.
Most guys don't want to spend any money unless they feel they have a great shot at taking a good sized hog. Just my .02 cents and I don't want any change back.
