I share a "creek" with an adjacent club. The boundary lines for our leases tend to cross back and forth, and we have agreed on the creek being the line. That said, if they shoot something that runs over on me, they let me know and vice versa. I talk to their guy every deer season via text, sometimes we share pic's and information. He seems nice enough.

My other adjacent landowner, I wouldn't pee on if he was on fire. I'll let the timber co handle him.

I would go talk to your neighbor. Give him your contact number and if he shoots something that runs back over on you, tell him to call you and you can meet him at the line to track it. Doesn't mean I wouldn't hang a couple cameras back there, but you might be surprised. Then again, he might be a total douche, but then at least you will know that upfront.
