Basically Your allowed 1 buck and two anterless but your breaking the law if you shoot them at night. The landowner needs to apply for depredation tags for you to legally hunt the deer without spending money on a license. He can kill all the deer he wants on landowner permits but they need to be checked in to be legal. if you use his landowner permits, again your breaking the law. It's up to you but but careful, The CO's today are "cops" and you could loose your equipment, hunting privileges etc.

I have zero interest in breaking the law.
