I would keep any food plots off the property line. I would clear so I could fence and move down both sides of the fence.
Definitely clear the actual property lines.
Ever hear of eminent domain?
It's adverse possession, not eminent domain.
It changes by state, but as long as you deny access within a period, it generally prevents it.
I'm all for a fence being right down a property line, but as a fence builder, make sure your deed lines up with your neighbors. It's a pretty frequent problem.
But I also wouldn't spend the money to fence that many acres without having stock on it. It's not going to slow anyone who wants to come over anymore than a sign on a post. It's about like locking your door, just keeps honest people from opening it.
