Another thing I've learned is that when a person has pissed someone off enough to have them damage stuff they've usually pissed off a few others also, whether they know it or not. 35 acres access could have been terminated simply because others in addition to him may have also taken up using that road. Other than being a-holes the OP has no proof at all that the people he suspects damaged anything. Should have never used these dudes property no matter how convenient. They are not your friends and should've have been kept at arms length. Hi and bye, nothing more.
You might be on to something Bueller. Maybe the other leasors caused an issue that I don't know of that had these guys a little riled up. Then when I was on their road, it caused them to snap. Or maybe they have one of their bait piles close to that road and they didn't want to me to know about it, maybe they were even there and when I drove by I ruined their opportunity to poach. Regardless, I was back at my property today and looked things over again in daylight, I repaired my tree cages and put out more cameras. I am certain that whoever did damage my stuff came off their lease and access road. The one that I had used of theirs. I am assuming (not accusing) that it was them, but I base that on a lot of things that has me relatively certain.
I can be sure, aside from the cordial chat with these guys (if they stop by my place, I don't seek them out) I haven't engaged them in any other way to piss them off. Heck, in general I don't see them except to wave when they drive by at night in their trucks (my light inside is on, they can probably see me, so I wave). There really isn't anyone else in this area except for the other group of guys - great guys - that lease. I text and chat with them and we've got an agreement to look out for each other (one of them is actually law enforcement of some type, and they have the same concerns about the slobs). The state game lands near me is narrow at the public road (like 80 ft wide), so no one comes up there to hunt it, yet it is a lot of land once you get far away from the road. I say all of this to point out that this is truly a remote place. I can spend a weekend there in the summer and see no one for 3 days; no one else to piss off.
At this point, I'm going to continue to collect evidence of anyone that trespasses on my land (I'm not sure what I'm going to do when I find someone has).
I'm going to continue to be cordial to the slobs;
NOT asking them for use of their access road.
I'm going to take my utility trailer to my property and leave it there (I've got to figure out a way to lock it and a way to keep porcupines from eating the plywood and rubber)
I will haul my ATV the few hundred yards to my lease and back as needed.
Through hindsight (never would have guessed something like this would happen) - these things are what I should have done all along.
