I grew up on a farm and this is how it got posted....Doe season.... a group of sports who bought license, stopped at the mailbox pulloff next to our barn, having seeing a group of doe, cut across our backyard...They all bailed out right there...that got our collie barking and my mother to investigate.....she confronted an individual less than 25 yds from kitchen door ,who immediately told her she should get ahold of that damn dog....she had a better idea, she got ahold of the State Police and they shut that down right then...So my Dad posted and if someone came in and asked thay got permission and if they didn't thay got prosecuted..as in poaching...With the scum wandering around today who can blame them....
