CAHermit,
Since you are posing a hypothetical scenario, I think this thread would be better suited as training material.
However, given that you have posed the question, I will ask another, that I would rather have you ponder than respond:

Do you have caches in all likely egress directions?

If not, then when TEOTWAWKI you are scrod.

Expert tutelage in caching is one of the reasons for which I owe a great deal of respect and gratitude to our liberated POW FalSarge.


I would gladly lay aside the use of arms and settle matters by negotiation, but unless the whole will, the matter ends, and I take up my battle rifle, and thank God that He has put it within my grasp.

Audit Fort Knox!
