The black community of the Sourland Mountains included war heroes, a man who stood up to Charles Lindbergh, and an enslaved woman who beat up her owner and escaped to live past the age of 100. Their stories have rarely been told. Diccon Hyatt and Joe Emanski interview authors Elaine Buck and Beverly Mills, whose new book, "If These Stones Could Talk," tells the story of these and other black residents of the Sourlands.
