I just put two wild hogs in my freezer a few weeks ago.
About 150#’s of meat.
Got another 15 to 20 pigs still roaming around.
How long would that pig meat last without electric power to your freezer for - say - 8 months?
And the other pigs running around - maybe 100 pounds each - how long would they feed a family without a freezer? Each pig would last less than three days unless you have the means and know-how to dry preserve meat. Then again every other family in the area will be after the same pigs - so curing them might not be an issue.
If the SHTF don't plan on those pigs or any other game being alive but a few weeks. Squirrels, rodents, domestic animal, birds, and snakes will be the next thing on the menu. A good 22LR and years worth of ammo is a good investment now. Also learn what the the Indians ate and used for medicine in the area you lived. Skunk Cabbage, Cattails, etc.
