Read the excerpt from "Choice: A Tribute to Dr. Martin Luther King, Jr.” by Alice Walker.There is a cemetery near our family church where she is buried, but because her marker was made of wood and rotted years ago, it is impossible to tell exactly where her body lies. In the same cemetery are most of my mother’s people, who have lived in Georgia for so long nobody even remembers when they came. And all of my great-aunts and -uncles are there, and my grandfather and grandmother, and, very recently, my own father.
