It was a carnal connotation in my youth 60 years ago
Corn much less ear corn wasn’t common in Mississippi then as a big crop
Cotton was still king and beans second
Man the Midwest is super corn country
I drive thru it every couple weeks
From southern Indiana to Battle Creek it’s like a carpet
Some of the corn cribs I helped empty were probably built before the great depression. Square nails, beams fastened with wooden pegs. Some rat holes were so big they were patched with paint can lids. Ear corn doesn’t flow very good. It can jam up and plug a hole over a foot in diameter.
When I was 18 my dad and I burned down a couple of old cribs. I walked through them first, reliving some memories. Those steel grain shovels were already heavy, without any grain in them, for a little kid.
When shoveling, you scooped at floor level. They wouldn’t penetrate the ear corn.
