i've had only one bad experience here in southeastern Vermont, when we first bought the property. I had very expensive livestock (high end alpacas) and we posted the land for safety reasons... all the neighbors did because they didn't like icky guns... one morning just before dawn the stock dog went nuts, and the house dog was very agitated... went down to the barn and both dogs were pointed in a more or less easterly direction barking to beat the Devil ... took a stroll down that way and found some flatlander sitting in a screw in stand... four or five empty beer cans at the base of the tree ...
i told him that the owner was a psychotic madman who'd sooner blow him to perdition as look at him, and if he had half a lick of sense, he get gone before something went really wrong really fast... he claimed that he had the owner's permission to be here, that he'd been here for years, and he'd do what he wanted because this was a free country, and bla bla bla ...
it was about three weeks before the deer season opened, and i told him that he did not in fact have the owner's permission, and i would know, inasmuch as I AM the owner, and we could wait for the game warden, or he could leave now. clear that rifle and let the bolt fall free... Win Mag 300 ... round chambered, safety off...
he was so drunk he didn't know which direction was North... i was a sporting fellow: i didn't shoot his sorry a$$. (but i did hang onto the bolt)
never had a problem since, so i guess it was a one off, but i still have the property posted ... it's not the round with your name on it that should concern you: it's the one that says "to whom it might concern."
