I was born in Dubuque, Iowa, and at age ten moved with my family to Clinton, fifty miles south along the Mississippi River. Outsiders tend to think of Iowa as flat. Much of the state is, but where I come from the bluffs rise straight up out of the river. Dubuque has an operating cable car (funicular railway) that a wealthy banker built to carry him from his office in the floodplain to his home on the bluffs 300 feet above. The view out over the river into Illinois is spectacular.

Others thought so too. All over the area are Amerind grave mounds looking down from the bluffs. One of them's on the farm that belonged to my father-in-law.

My dad was an electrician, but nobody in Iowa is very far from a farm. Family friends had farms when I was a boy; my wife's family were and are dairy farmers. I've spent enough time on and around some of the most productive family farms in the world to have a feeling for the life.

Which is very, very hard. The work has to be done every day, no matter how you feel or what the weather's doing: you can't call in sick and tell the cows that they won't be milked this morning. The machinery is dangerous beyond the imagination of a modern factory worker; the organo-phosphate insecticides were invented just in time for World War II, where they provided the Nazis with the first nerve gases; and even city-dwellers know that if anybody gets rich from agriculture, it isn't the family farmer.

The characters in this story are modeled on real people but they're not my in-laws. The farm is one my in-laws owned, including details like the curio cabinet and the hunting rifle.

I frequently use a story that has greatly impressed me as a model for one of my own. This isn't quite so direct a case as some, but I want to mention the similarities to Theodore Sturgeon's "Killdozer." The title (which was the genesis of the story) comes from Robert Browning's "Childe Roland to the Dark Tower Came."
