"TEOTWAWKI- The End Of The World As We Know It"

I suggest thinking the unthinkable from time to time is exactly what this ETS forum is all about. In the case of this thread, I would suggest that it points to seeking experience securing food without firearms - surely a useful skill in many conceivable situations - and perhaps widening your palate to include foods new to you.

Even here in California, which bans most trapping and netting of game animals, some study of the Fish & Game regulations suggests many other legal means of "thumping chow."

"Gathering" is an elastic term that might cover many food acquisition techniques. With a California hunting and fishing license, for example, you can both trap and hand gather coastal foods like crab, abalone [special regs and report required], bivalves [including but not limited to clams, mussels, and oysters], seaweed, and algae. On land, mushrooms, edible plants, and plant products do not move fast enough to elude the wily forager. Rattlesnakes may be taken anywhere, any time, and by any method without limit; while there is a two-a-day limit on other snakes.

Hook and line fishing techniques allow seeking saltwater and freshwater fish, turtles, and frogs with certain legal requirements. In some cases throw nets and bow-and-arrow may be used.

Then there are things like snails and insects.

No ammo required.
