So, I have two different perspectives that I've used to come to a reasonable compromise. First, I own land. The neighbors own an adjacent field and hedgerow. They have several stands at the edge of the field just across the rock wall that forms the property boundary, as well as two shooting towers in the fields themselves. While I understand that they used to have a sanctuary where they just had to wait for deer to wander their way, and they may resent losing it, in the long run I think that the habitat improvements I've done will benefit everyone. For now, they need to deal with the fact that I'm actively managing and hunting my land, and I have to give them a bit of space on the edges so they're not completely locked out of the game. My tactic seems to keep relations friendly and I haven't had any boundary issues, despite the boundary stands.
Second, I lease land. It's a long narrow piece of property that's mainly fields and hedgerows until the very back. Many of our stands closer to the front are by necessity placed where the hedgerows meet the field edge near the property boundaries. In all cases we've clearly communicated to the adjacent property owner that we will never, under any circumstances, shoot across the boundary. It took a few years, but I think repeated adherence on our part has earned their respect. However, there's still the occasional posted sign that shows up facing our stands to remind us lol. Again, we managed to cultivate good relations through a culture of mutual respect, even if the adjacent owner didn't like where we'd placed our stands.
In both cases, I was blessed with reasonable neighbors who were willing to listen and to discuss. I've heard of nightmare scenarios, though, so I count myself lucky. I would always try to approach the neighbors peaceably first before going in guns-a-blazing. Good neighbors are worth their weight in gold, and you'd hate to alienate a potential ally by bull-rushing them.
