Jerry: you're referring to the 1985-1990 period of the Iditarod.
1985 - Libby Riddles won, first woman to do so.
86, 87, 88, 89, 90 - Susan Butcher placed 1, 1, 1, 2, 1.
In 89, it was close and they didn't know in Nome who was ahead. As the winner approached, like in the delivery room, a cry went out, "It's a boy!"
T-shirts of that time said, "Alaska, where the men are real men. And women win the Iditarod."
The first Saturday in March (Iditarod Start) is Susan Butcher Day in Alaska (she died pretty young a few years ago).
I bumped into her in a gas station, and even before I recognized her, had a strong sense of, "this is a woman who can take care of herself" like facing down a moose on a distant trail or caring for dogs on the trail at -40.
