I read stories aloud at every stage. I listen to my writer friends when they kindly offer criticism. I listen to my husband when he tells me something doesn't seem right. I have my mother's boyfriend, Loring Janes, read to make sure I get everything right with the machines and guns.
I've always tried to be fair to my subjects. That's easy when they are as likable and admirable as Lewis and Clark, or Eisenhower.
