BS.
Yes they do wander all of your property, just like they own it! This has happened to me on my tree farm. When I caught him "twice", he said he can come here anytime he wants or needs to. I called the sheriff on him and not a thing was done. No hunting or fishing taking place on the land. He not only crossed my well posted land, he also crossed my gate.
They can do whatever they want, when they want. It's the biggest bunch of BS I've dealt with. If you think you have rights, when it comes to your property, the wardens can go anywhere they want.
