I was born in 1943 and my mother told me (dad wouldn't talk about it) how my dad did the same as your father except he was plowing behind a one horse plow from sun-up to sun-down.
My grandmother (mothers mother) would give a free breakfast to who-ever chopped her cooking wood for the day each morning.
She had to change that because they kept coming earlier and earlier to beat the next guy there for the meal and were waking everyone chopping wood at 3:00AM.
My dad did tell me how they had to hide the plow down the water well when the bank came to repossess it.
I can't even begin to imagine this..
Poor people don't know they are poor unless someone tells them they are. We learned to survive and I would trade those hard times for what we see coming.
