Once the system collapses, and the war is over and you make it out of the FEMA camp. You will find yourself having to get back on the land. Don't get squeamish now, these things are gonna need doing.
Ok, you have your pig cut into pork. Remember, the grid is down, no freezer. This is how to salt your fine pork cuts to preserve.
I've hunted wild pigs for a long time. The best tasting ones are those that still look like farm pigs. And the younger the better the meat. On a hunting trip you always should bring and ice chest full of ice and a carton of salt. Then you gut, skin, and quarter the meat and soak it in the brine to cool it quickly. Without the ice, you can hang the quarters out in the evening and nighttime air but wrapped up in thin cheese cloth to keep the flies off it. Pork has to be treated quickly -- either salted or smoked or boiled and jarred -- or else it will spoil. It is unlike venison in that respect.
Obviously, meat should be jarred or in some way preserved. Make a Zillion jars of pork & beans !!!! I liked winter meat storage, since you have unpowered refrigeration outdoors, just supply the metal boxes with shelves....
