No better protection than befriending a neighbor and giving him or her exclusive access to your place. We live on our place now, but for the first couple years one of our neighbors was given trapping and walking rights to our farm (except deer season). He now has permission to also take as many bluegill from our pond as he wishes, but needs to throw back the CC and LMB (not really an issue since this winter's fish kill). Choosing the right person is critical. This fellow (and his wife) leave no trash and are respectful of property rights. He is also a good shot but not stupid. He has called us on several occasions when unknown vehicals have gone up our drive and we were away. We have not had any real issues since I made it clear to the local tresspassers that I would defend my property rights, but another set of eyes is a good thing.
