Roland McElroy’s latest book, “The Best President the Nation Never Had: A Memoir of Working with Sam Nunn" was released by Mercer University Press a month ago today. So when McElroy talks with local authors on the subject of writing memoirs during The Write Place Writers Festival this weekend at the Averitt Center for the Arts, his personal example will still be fresh from the press. A fee for writers’ workshops was advertised, but all elements of the festival have now been made free and open to the public through the support of a corporate sponsor, Statesboro Magazine editor Jenny Starling Foss said Wednesday.
