I tell you I am a very nice and gentle spirit until it comes to trespassers. We have had our fill over the years on the farm of finding gut piles and running off trespassers that claim to be looking for a wounded deer, but can't produce one drop of blood anywhere, and sometimes they don't seem to even be on a track in the snow. We also have a load of neighbors who think it is perfectly fine to hunt right on the property line with their stand in a fence line tree and them setting so their shooting side is facing us; they have to stand up and turn around 180 to shoot on the property they are supposed to be hunting. Then there is the neighbor with the shooting shack setting three feet from the fence who sets facing the fence with his back to his 5 acres with no window on that side. Or the guys bow hunting in another neighbors back yard of their one acres lot with their pop up blind setting on the fence line right in a gap in our pine trees we planted to screen off all the neighbors. How likely is it that they could shoot a deer and not have it leave the property if it was ever on it in the fist place? So when one of them comes looking for a deer even if they ask I tell them to head home unless they can show me blood starting on their side of the fence at least. I get soooo tired of seeing the orange army march up and down the fence line. I have had three very close calls with shotgun slugs so I have had it with all that. I don't even feel safe hunting within 100 yd. of the property line.
Don't get me started on the construction works that used our pines as a toilet for a good part of a year while building a house for another new neighbor, but that is another trespasser type along with the dogs, kids, and ladies on horses who think riding on the property in the middle of gun deer season would be as good idea.
So what I am saying is ask first because some of us have had all we can stand from the neighbors and don't care to have you just do as you please. It could be your first hunt on an adjacent property, but you have no idea what the neighbor has put up with in the past. Even with all my experience and more new neighbors on the way, I would let anyone who asks come get a deer if they show blood on their property leading into mine. If you feel you can't ask then make sure your deer doesn't leave your property. I would recommend anytime you start to hunt a new place that you meet all the neighbors before you hunt, tell them you will be hunting in the area, and ask if you can get their phone number to ask to get a deer if one should cross the line. I think that would go a long way.
