My family has a bunch of land so I hunt it a lot. We butt up to some land locked state land so there has never been an issue with trespassers until someone started hunting the state land. Inevitably, they started hunting 50 yards on to our property from the state land. I took their stand down, took their trail camera, neatly stacked it all up, and left a note in a plastic bag that said next time I find your stand on our property, I’m keeping everything. Didn’t have an issue with that individual again. He more than likely didn’t know where the line was, but ignorance isn’t an excuse.
I have gotten some random people on camera on an ATV a few times, and I couldn’t figure out who they were. Until one day I saw a neighbor from a couple miles down the road with the same ATV. I confronted them and said your ATV was on our property with 3 kids on it. Don’t let it happen again or we will take action. They denied it was them, but I haven’t seen them since then.
It’s super irritating when someone just helps themselves to something that isn’t theirs. We spend a lot of time & money to maintain and own the property. Certainly isn’t open for visitors without permission!
