A few rows of trees planted on Brads side of the line would be solve this so-called problem, wouldnt it?
Looks like his field is cleared right up to the line allowing him to hunt right up to the line. Heck, he can literally see the deer as it crosses the property line from his neighbors land. He is perfectly legal to shoot it, too! So, he is Line Hunting just as much as the other guy. They are both perfectly legal and well within their Rights to hunt just as they are doing now. If there is a problem, then the only thing they can control is their own actions......not that of their neighbors.

And, you are not going to have any Luck getting any of the GWs that I know to take that Bait. You will most likely get a lecture about placing a feeder on the line and/or clearing and planting property lines. They are not naive. Nor do they have the time to act as Counselors to whiny people hunting lines complaining about their neighbors doing the same.
