Heres my advice you can take it or leave it. I have had quite a bit of problems over the years with some certain individuals trespassing and stealing my stuff. I hung signs, called the police, and complained to the property owner that was allowing them access to his 15 acres where they would promptly cross over onto our two hundred acres. I did this on a yearly basis, and I found that I was begining to spend more time trying to keep them out than I was hunting. They were literally ruining my enjoyment of hunting! Have you ever had your favorite tree stand stolen during the peak of the rutt? It has happend to me three times This year I finally gave up. I decided I was going to just hunt and spend as much time in the woods as I could. I sat in one of my tree stands at the beginning of this years season and I said a little prayer. Now you might think this is corny, but it is the truth. I told God I give up. I can't stop these guys from stealing my stuff and trespassing. I asked God to please just let me enjoy hunting again, and let me stop worrying about things. Guess what? I have not had a single run in this entire season! Not a single stand has been stolen. Not a single person caught stalking through our woods. Even during the firearm season I never found any human tracks other than my own in our woods! It has been one of the best seasons for me that I can remember.
Make your presence in the wooods known, hang some signs, do what you can, but in the end don't let it ruin your hunting! Turn it over to God and let him take care of the rest so you can concentrate on enjoying yourself. Thats what I think anyway. Good luck!

The spirit of the woods is like an old good friend
