How do you figure it isnt that easy? I have seen it done on several occassions, and seen these folks cut every boar save them in a pen until they get a load and then take them and dump them in a spot that nobody has access to but them and they really dont have that much access to it. You put that many barrs that will grow faster and get bigger, and you have serious dog power then you will flat out slam some hogs and some nice ones at that.
If someone wants to cheat bad enough to do this then they will just find another way to cheat. I hunt deer leases, not a ranch or farm land and we dang sure dont ride around spot lighting till we see one and turn the dogs out on em. When we hunt our dogs put some hard work in! This is why we want a Barr hog to count, it about the dog not the hog!
