Ive been thinking about this, the desperate hordes of NPs. If you can secure your home, the best thing to do is starve a little and look dirty in public, appear as if you are suffering like the NPs. Line up for food and water like everyine else if its offered, no matter how much you have stored. It wont fool everyone in every situation but it will be a useful strategy to help many preppers get by and keep their supplies.

Also, get every family member familiar with a gun. Never let every adult/ young adult in the house be asleep at the same time, even if there is only two of you.
