Yeah, preparation is the key to success and survival!
I mentio ned earlier that I also keep a box or two of ammop for weapons that I do not own(yet) or know that other family members DO own on hand.
JIC, you never know what fate holds in store for you.
So I have a box of .357 sig and 9mm although I don't own either caliber weapon. One box was a mistake purchase(from the pimple face behind the gun counter at wal mart) the other box was given to me.
I also like air guns because they offer a relatively quiet way to hunt/eat while not giving away your position to someone. So I keep several tins around(they go fast)
