An option to think about that can be made at home is a basic bow and arrows. It will not replace fire arms but its a economic option. Water is life, but if you live in an area were water is plentiful like I do storing water like a mad man might not serve you well. Try not and get over whelmed and take a inventory of what you have on hand and what the area provides. Start filling in the blanks from there. Hope that helps.
