Buy a lock on and once its up, chain it in with a heavy chain and padlock. then remove the last 4 or 5 steps (or last climbing stick or two) that way no one can steal it and would be forced to bring their own ladder out to get your stand. doubt he or they will want to put forth that much effort into getting it. my dad inscribes our last name into his stands jsut in case as well. Just remember, if you put it out of reach, they cant get it and usually wont put forth much effort into getting it, they want a quick swap of the item(s) and get out.
