I've dumped the dollar to the extent possible, bought silver and gold, and keep a small store of cash in my safe. I have set up a fairly large garden (raised beds), which produce more than enough food for my family for the year, minus some staples (flour, rice), which I have stockpiled in bulk. I have learned to can vegetables and meat, and do so with whatever I don't eat fresh. I'll be getting chickens and goats this year as well (after I fence off the front yard).
I also have my guns (9mm, .357 mag, 22. pistol, .22 rifle, shotgun, .306, and a black powder revolver), and I am going to be getting my father's reloading accessories, and I plan on getting a lead casting kit soon, along with a bunch of lead shot. I may also pick up my Uncle's machine shop equipment.
