If its not your own property, I don't know if you really can do much. First off, try giving him the benefit of the doubt that perhaps he didn't see your stand. If its a good spot, he may be every bit as good a hunter as you all for finding the location. Yes, I would really be bothered having a guy put his stand up this close to mine, I wouldn't respond well, and I'd probably just move. Even still, try the scheduling out, maybe you'll both get really nice deer and maybe you can be friends. After all, he's demonstrated that he can find a good place to hunt, and he may be a good guy. Look at the bright side, and maybe you all can get some other good places to hunt. Look to make friends in the woods, not enemies...Still, I feel for you cause when you get that honeyhole, it feels really good and to have someone else find it stinks. Good luck
