It was a dream, then a place, then a memory. My father built it near the Suwannee River. I like to think it was in the heart of Florida, because it was, and is, in my heart. Its name was Dogland. Some people say you can know others if you know the central incidents that shaped their lives. But an incident is an island in time, and to know the effect of the island on those who land there, you must know something about the river they have traveled. And I must warn you before we begin, I don't know that river well. I visit that time and place like a ghost with poor vision and little memory. I look up the river and see fog rolling in. I look down the river, and the brightness of the approaching day blinds me. I see shapes moving behind me and beyond me, but who they are and what they do, I cannot say. I will tell what I know is true, and I will invent what I believe is true, and that, I think, is all you can ask any storyteller to do. I learned the Nix family history from the stories Pa told. Even at the age of four, I suspected that Pa's stories might not be perfectly true. When Pa said we Nixes came to North America as indentured servants working our way out of debtor's prison, Grandma Bette would make a face and say he couldn't know that. When he said we Nixes had Lakota and Ojibwe blood in our veins, Grandma Bette would say she wasn't prejudiced, but it simply wasn't so: she and Pa and his brothers and sisters were dark because her people were Black Dutch, from a part of Holland where everyone had black hair and black eyes. And then Grandma Bette wouldn't say a word for half an hour or more, a very long time for Grandma Bette to be quiet.
