It sounds like those guys need to go back to hunters safety and learn ethics. You do not go bombarding onto someone elses hunting property just because they shot a big buck. They need to learn that shooting the spike buck ruines that deers chance of growing to a mature one. If you talk to those guys and they still keep hunting the area I would try to find another area to hunt and chances are you will get a shot at another mature one. By then hopefully they will figure out that maybe they are going about things in the wrong way and instead of hunting you and your spots they will learn to hunt the deer by gaining knowledge of the biology of the species.....if they continue to act in the way they are then they areNOT true hunters.
