has this happened to you and what would you do
A few years ago I was walking into my stand on my 10 acres and was confronted by a hunter that was hunting near the property line on the neighbors. I was also walking the property line to get into my stand, but I was on my side of the line. He was pissed, but he calmed down when I explained who I was and that I wasn't trespassing. That night, I took a different route back to the house, then waited for him to get to his truck. I explained that I thought he was hunting a different area, and he said he usually did. We came up with a plan that based on where he parked his truck, I would know which area he was hunting. We also worked out how if I was out hunting before he got there how he would know, so he could stay out of the area. It worked out well, and we didn't ruin each other's hunts.
Just like public land, get between the deer and the other hunters.
NOW......If the guy is moving in on you and just being a dick to be a dick....well then thats different! I would mothball his stand and every thing within 30yds on the ground from his stand! Id make it look like it snowed out around his stand! If he likes hunting in the early mornings...even better! Those little wind up alarm clocks you get at the dollar store...?...trust me when I say the look on their face is priceless when one goes off at first light and then every ten minutes in a different location hidden like easter eggs around his newly "claimed" spot! best ten bucks I ever spent on "hunting gear"!
Just note...you will probably get asked to leave by the land owner if he goes whining to him but oh well....you had a good laugh at the dick head land bully!
Just out of curiosity, what is the land owner like? All too many times we give our opinion and really don't know a whole lot of the background or the full situation? The reason I ask is 1. would he give you the new guys name or phone number? 2. Would he be willing to talk to the new guy and say, "hey, you need to honor your spot, you were here first." 3. Would he be willing to lease it to you exclusively in the future?
Best of luck with a frustrating situation.
1. No 2. Begin looking for another place to hunt, and perhaps spend some time with the owner discussing "exclusive" rights to hunt the new place once I acquired permission. If it took a chunk of $$$, a few bottles of the owner's favorite adult beverage, some work during the off season, or something else in order to have the piece of mind that not dealing with this would bring...it would be more than worth it to me.
I suppose option 3 may be to discuss these things^^^ with the owner of the current piece of ground you hunt as well. It may not help you this year, but if you're wanting to keep sole access to this piece in the future it may help for future years.
