I don't know about the rest of you guys, but I grew up in Oklahoma and SW Missouri in the 50's. We always lived in the country; my Dad was a construction foreman, and always had a job, but we were poor...but then so was most everybody else. I learned to hunt and fish as soon as I was able to bait a hook and shoot a rifle. In fact, My Dad was a country boy, and I learned from him. We supplemented our table with about everything edible you could think of, except maybe mushrooms. We hunted squirrel, rabbit, quail, ducks and geese and caught all kinds of fish. In those days, deer and turkeys were pretty well hunted out by the depression meat hunters like us. We gathered possum grapes, wild black berries and boysenberries...even wild strawberries when we could get them...not to mention walnuts, hazel nuts and hickory nuts. My brother and I walked about a mile to the bus stop, and many was the time we picked our lunch pales full of possum grapes (mmm...Mom made great jelly).
There were folks in Oklahoma and Missouri that I don't think would have survived, with their big families, if they couldn't live off the land...and in SW Missouri and Eastern Oklahoma, you could. There were no wild hogs in those days that I know of; I think they would have been hunted down to nothing had there been.
I think that the economy and change in society from rural to urban has pretty much eliminated living off the land any more, so we don't have hunters killing all of the deer...and hogs, had they been here...like we used to do. It's done mostly for sport now, not for survival. Food stamps are easier. Recall my Dad telling me that when I was little...pre school...I ate more venison than any other meat; but we lived in Lawton at the time, one of the few areas that had deer, and every one poached them.
