The public land I hunt allows no equipment to be permanently attached. I would'nt leave my gear there for the above reason but also because it would tempt people of low character. Not only is theft of equipment likely, or drawing attention to your spot, what if you came to it and another hunter was using it and was adamant about staying there. Is it marked to prove it's yours in a way you can prove to them? How would you handle the conflict someone else clearly creates? How close is the nearest warden to settle a dispute and what priority would they give that circumstance?
