The American people have spent the past couple centuries specializing skills and improving the quality of life so that we can sit in a warm house in the middle of winter and read a book, instead of spending the whole day chopping wood, hunting your dinner, hauling water and doing the hundred other chores that needed to be done back in a log cabin on the prairie in 1815.
I've got acres of woodlands around my house and I can live off the land in my current house if I absolutely had to. I choose to wait until or if I absolutely have to. So in meantime pass me another beer, put a decent movie on Netflix, and check the temperature of the turkey in the oven. The turkey I got at the supermarket.
The only thing I would point out (and without knowing your specific situation—this might not apply to you) is that many, many folks are thinking they will be able to go into the woods next door and live off the land.
In a SHTF situation, the local forests will be empty. There are no “seasons” and no limit. People who understand how to cure meat for preservation will clear out anything larger than a mouse in two weeks top.
