My beef is with snowmobilers who ignore my no trespassing signs. And I live on a dead end road.
I posted my property to keep mushroomers and hunters off but signs are ignored. Mushroomers are the worst. Two signs were damaged by these jerks. During mushroom season, which is rapidly approaching, I will be doing a lot of load development for a couple of new rifles and some plinking as well. I have a good backstop even though I live in an isolated area. The locals know I shoot competitivedly and shoot a lot...the "outsiders" will not know if some weirdo is blasting randomly. LOL
As to the OP, I would want my new neighbors to intorduce themsleves but not early in the morning. I have a gate I can lock and normally just clip it shut during deer and mushroom season. But if you want nobody to enter, keeping a gate locked is a PITA and it gets old quickly. If your problem is with locals, a talk is all that is usually needed. If that does not work, charge them with trespassing and word spreads very quickly. If you are a "good guy", the others will accept it; but if you are a jerk, be prepared for more problems.
I had a local who I locked in when she trespassed to mushroom. She was a member of one of the major families in the area. When she came to my door to get the gate unlocked she said, "Don't you know who I am?" I said, "I really do not care..you are a trespasser. I can have you charged for not only trespassing but theft." Everyone had a big laugh about it when the story got out, and it stopped the locals from trespassing.
Good luck with your issues. No one right answer as it depends on you (how you are perceived and your personal quirks), your area, and the kind of trespassers (locals or outsiders) you are dealihg with.
BTW, you cannot draw a weapon or brandish even on your own property if things get ugly. If they do, you want to be the first to call law enforcement or the DNR. They will normally side with the property owner unless you do somethign really stupid.
