I have loads of cameras and can see who is there before answering the door. If I notice people canvassing the neighborhood with clip boards, I often lock the gates.
My son is threatening to put a sign at the end of the long driveway. It would read “Warning. Beware of dogs. If you get by them, don’t piss off the old lady at the end of the drive way.” I did almost shoot him one night when he tried to hook to one of the trailers while driving someone else’s truck. He’s a nice respectful young man.
Would seem only fair for the recipients of the information to take names, maybe photos, to keep an online “list” of these government “volunteers.”
