RE: WHAT WOULD YOU DO...HONESTLY...
I would have to do the ethical thing, and not shoot him. Its bad enough to be in that situation, what you could do is go to the landowner that the land is on and just ask him if you could hunt on his land. I pretty sure he would probably let you unless he knows that deer is there too. I would just let him be, and even if you hunt there gun season you could ask the land owner so you can hunt on it then too. That way you get the best of both worlds.
