I've leased a piece of ground for many years and have had little problems with theft or trespassing until last summer. Late last summer I went to check trail cameras only to discover all of the sd cards had been stolen from the cameras as well as one camera which I didn't have locked. A trophy rock I had placed out was also missing. I replaced the sd cards with the intention of installing small locks on the camera doors the next trip back. About a week later I come back and once again all sd cards show up missing. That same evening I get a phone call from a guy who claims to have bought the adjoining farm to the NE. He had gotten my number from the landowner I lease from and called to introduce himself. He seemed rather curious and was asking all kinds of questions. Sensing something wasn't quite right with this guy I told him that I'd recently been having theft troubles and was going to put out hidden cameras in attempt to catch the culprit. I made it clear to him that I did not tolerate trespassing. He said he totally agreed with me and that he would keep a lookout for anyone suspicious. From then on I had zero problems the rest of the summer which seems awfully coincidental. Fast forward to now. I was just at my lease and while I do not have cameras out yet the problems are starting again. A trophy rock I just placed out two weeks ago was missing. Same location as last year. It's a long walk back there and no way to get there by atv or vehicle. I'm thinking it's the neighbor guy again screwing with my stuff. Any suggestions what I should do?
