where would a person who is new to hunting learn this, any links you can message me.
One of the reasons they fared well was they were in ranching and farming country. While the dust bowl wiped them out, lost their cattle, lost their crops, they were hardened rural folks who had lived a life where town was a day or more ride on a horse. They had longed since learned to live off the land and neighbors were a long ways off, they had 3000 acres and 8000 acres amongst the family.
As stated above, population density has a lot to do with game and a understanding of when and what to gather. Its really a combo of hunting and fishing for proteins.
Its also how you preserve the catch...if you do not have a smoke house YOU WILL STARVE to death. Neither meat nor fish will last much more than a few hours if the temps are above 40 degrees. This means almost all game hunting will take place in the cold of winter, fish will need to be cooked on the bank in the summer if distance is further than a few min walk. Reality is you will need to gather proteins in the cool months and preserve for the warm months or go hungry. Summer brings on eating what you kill where you kill. Also some animals get worms and other issues that cold weather will kill. Dad said you don't hunt to eat ill after the first freeze.
To survive after the SHTF you will need to get far from any city or town of any size. You will need to hunt the most rugged an rural areas you can get to. Most likely you will need to preserve you meat at your camp site as it will not get it out with spoilage otherwise.
If you want to learn and you don't have a father/grandfather like mine that truly survived in a SHTF situation the you need to study how folks lived thru tough times in rural America. How folks lived prior to electricity and telephone.
FEW survival books are of any use cause they do not know either, they have rarely done it or like the survival shows on TV where they have a heli standing by in case someone gets hurt and a support crew of as much as 100 people.
Look at how folks lived prior to about 1920. Guess not many folks around from those days anymore, but remember my Dad/Granddad did not have fancy knife or a load of tactiKool junk hung on some semi-auto, no fancy waterproof clothes, water filters or anything else. And they MADE IT! Something FEW on this forum will do.
