First defense is Dakota 4 zone alert, with one for the driveway down near the road, 2nd is two dogs that love to bark at any car they don't know, 3rd is fencing rowed to funnel anyone coming in to have to use the driveway, and 4th would be 44mag on headboard, Ruger P89 on the wife's side, and numerous other always in range. There is more, but I don't like to tell just anybody everything.
