Interesting Sides Here...
This is really interesting to see the side of those who own acreage that makes excellent hunting and those who don't but want to use it.
I get pretty darn territorial about my property, be it 1 acre, 4 acres, or 500 acres.
Most could relate to their house whether they own or rent, you have a yard, usually front and back. If you came out to investigate the sound of an ATV and found some clown hauling in building supplies to make a stand in a tree in your backyard you are going to be one ****** off confrontational dude. There is absolutely no difference if it's a hundred or a thousand acres, it's private land, it's yours, and it's your right to keep it untouched and pristine if that's the way you want it to be.
I grew up surrounded by ranches and mountain property as big as 20 and 30 thousand acres. Where I grew up you didn't just go on someone's property without asking for permission. Most land owners will allow people on their land who show them the proper respect and regard for the fact that they own the property and it is their right to keep people off if they choose to. This shows the landowner that you are responsible and respectful.
The kind of people who would not only trespass in disregard of posted private property but would go farther than that with ATV's and building hunting clubs in the trees are disrespectful pigs. Disrespectful pigs shoot cows and think if they can get away with building a stand they have the "right" to do anything. I know ranchers using BLM land that deal with cows being shot every year. Some get cut up and quartered with a chainsaw for the meat and others get shot because they can be and a couple of steaks get cut off to cook by a fire. The kind of person who would do that deserves whatever works best to deal with it. The areas I have in mind you couldn't get law enforcement into, it's too much of a wild west situation, they are literally afraid of being shot by people who have a total disregard for the law.
Say a piece of private property is big enough that several parties have built tree stands, and it gets into disputes over them that results in people getting shot. Guess who gets sued for the unruliness? The landowner, that's who. Their homeowner's insurance is a big target for liability and that's who will get sued, not maybe, will be.
If a nice respectul guy comes to me and asks to hunt on my property it's going to come down to if he can hunt without an ATV, without building a stand, and without leaving any signs behind that he was there such as trash. I see someone in a stand that they built without my permission I'm going to tell him under no uncertain terms that he is to be off my property or the sheriff is going to handle it from there. I'm going to be carrying a knarly sniper caliber rifle and point out what a great target they are sitting alone in that tree. It would be very hard to enjoy hunting feeling like you are a target.
Coming back to check and he's still there it's hard to say whether I'd leave and go get a sheriff or escort the guy to the edge of my property walking behind him. I'm definitely an escort him off the property sort of guy, some people you argue with, some you don't. I know if a guy has an ATV on my property I'm not even going to talk to him I'm going to get the sheriff.
Go back to that scenario of someone taking over your backyard in a residential neighborhood and see how that would leave you feeling before getting judgemental about a landowner getting territorial about his personal property, it's no different.
Added as an afterthought:
What I guess I was trying to say is that I wouldn't dare go on privately held posted land. I have known a lot of people including myself who are ranch owners, and I would feel a huge liklihood of simply getting shot and disappearing, my skin crawls when trespassing because in my world that has been the way it is, nothing else but the way it is. People post large land holdings within 60 miles of here because they have pot operations and they will shoot and disappear trespassers because there is a lot of money involved.
I guess it's different back east but I'll bet there's the same thing going on in parts of Kentucky, Virginia, Tennessee, Arkansas, etc. I came upon a still in Arkansas in private woods and I'm pretty sure those guys would have shot me if I hadn't run faster and hidden well. Trespassing is trespassing and things happen to those breaking the law in the first place.
