As funny as this may sound my entire family has talked about this. We live in Kentucky and everyone has at least one gun that is old enough to hunt and we go camping alot. I have some military training that would com in handy and my dad ande brother in law are both hunters. My mother and sister can both shoot and my kids....well....I can not think of anyone I'd rather have watching my back. Can't tell you how many wargames they have been the last men standing.
We like talking about this subject and have made plans in case it ever happens. Yes the planning is all in fun but it really helps with the movies we are making to try to pretend the what if and then plan what we would really do.
Between all of us we have the skills to survive. I'm not saying it would be all comfy cozy but we would eat and stay warm.
