Man that's a tough call. Legally, I think he himself would have to be in the pursuit of game with weapon in hand to be classified as a "hunter". Sady, Guys like this are "free to move about the country" conducting any activity with the exception of those they are excluded from. Hanging a tree stand is not hunting. He could claim to be doing it for "wildlife viewing", etc. Of course we know otherwise, but there is very little we can do to stop him. Stupid is as stupid does...it is going to be hard to change this guy unless he is caught redhanded. Good luck...talk to your warden and let him know how you feel. Maybe the laws can be changed to more specifically address these issues.
