With me it is my wife, my sons, and her daughters and mother. I don't even tell them, other than my wife, all that we have planned.
I have made it clear if we are circling the wagons they better figure on 2 things; 1) If you don't work you don't eat, 2) Bring everything you can carry of use to the family, food, fuel, tools, and firearms with you when you come. There is no way I can supply everyone with everything, and I won't try to.
Depending on how severe the situation is, the difference between economic downturn/depression or TEOTWAWKI, I am sure some of my neighbors will pool knowledge and excess vegetable garden produce to help out in a depression type situation, not sure what will happen in TEOWAWKI.
