"When I was a child and we put up loose hay on our farm, my job was to tramp the hay down on the wagon," Mary Olson explains casually to Nancy and me, as she starts to pull up her left sleeve to expose a long scare on the underside of her arm, near her elbow.
"This is where my dad accidentally put the hay fork."
She's grinning so we laugh too.
"Did they take you to a doctor?" I ask, expecting the answer to be negative.
"No," she says.
