If Laura had a remembrance book, there's one thing she'd want to put in it: her adventures in the American Midwest. The TV series, though, was only loosely based on the book series, and took liberties with the story over its nine seasons. Albert Ingalls, for instance, appears only on the show. Mary's husband, too. See how much you remember about the pioneer life of the Ingalls family and the town of Walnut Grove.
