I am not going to carry a firearm when I am at home. That is not to say that I dont have one close at hand but I am not going to walk around like a armed sentinel when I am trying to be at peace. That being said, my Wife and I have a plan. We pay attn to what is happening around our home and we look out for each other. We also network and communicate well with neighbors we trust. We each have specific jobs during a crisis and we know what they are.
We have dogs and they are one of the most important protections that we have. Not for attack purposes but for a warning alarm. We have always had large herding dogs because they are very very vigliant after dark and naturally alert to threats vocally.
We do have a good alarm, lighting system and landscape design that works against would-be prowlers. lastly, we have the house guns.
Life is a web woven by necessity and chance...
