I think that you always try to bond with the neighbors with the realization that many times they may be the actual trespassers on your property.
Then, when the sh*t goes down, you can and should always say "I tried to be nice about it."
However, as an absentee land owner, I have resolved to accept the following: You will always have to make efforts to protect your land; it is an ongoing effort. There are good days and bad days; just don't shoot someone on the bad days.
