3. A Fallout Shelter
Ideally, you will have your own shelter or bunker in place and well-stocked so that you can safely remain near home.
However, if this is not the case, you may be able to make use of an old bunker or fallout shelter that is no longer in use.
You will need to bring your own supplies with you, but this could give you a more easily defensible area to hunker down in than your house.
