Old folks use to say when I was a child you better hold on to your land to raise your own food and meat cause day is coming like we talking about. Grandparents use to take buttermilk,eggs butter, etc.and take it to town and exchange it for sugar, flour, salt, and goods they needed. Grandpa got his first carton of Coca Cola and would ration it to 11 children. He would kill like 10 hogs after Thanksgiving when it got freezing weather and feed his family all year, eggs from the chickens, milk from the cows, vegetables from the garden, hunted game to put food on the table.... and we think we got it better. I was raised on a farm and have seen both sides.....oh how the times have changed.
