What I was referring to when I said this is a little different is when you said "One time on property, no signs, upset landowner, call to police and landowner can follow through with charges." As I read the law it seems pretty clear thatif a person enters property that is "unimproved, apparently unused and unfenced (or not otherwise enclosed to exclude intruders.)" and leaves immediately when the land owner tells him to then he has done nothing illegal and can't legally be arested. The landowner can file a complaint but the charge wouldn't stick. Don't you see it that way too?
