Right, common sense goes a long ways when dealing with the public. But they can enforce it without the landowner. As in all cases, the GW does their job, what happens after that is out of their control even if they may have some input.

Now, the original question. Is it illegal/legal to hunt on another persons land without written permission on person.
I still say it depends. The "guest" part changes things.

2dogs, me and you may interpret this differently. With 100+ GW in the state, you can bet there is different interpretations.
