And the Savannah Book Festival just keeps getting bigger: Former Vice President Al Gore has been added to the mix, joining Dave Barry, Gregg Allman, James Patterson and the guy who writes the Diary of a Wimpy Kid books for kids. Gore's coming to hawk his latest book, The Future, and will give a free talk Feb. 16 at Trinity United Methodist Church. Afterwards, he'll take questions for 20 minutes. All the Book Festival details at savannahbookfestival.org.
