Which way's the Ark? From left, Tara Ekstein, 15, Melita Grant, 14, Elena Bobola, 14, and Kate McNeil, 14, of Sydney Girl's High School, gear up to re-enact the 1916 transfer of Moore Park Zoo animals to their new home, Taronga Zoo - by barge. Any child visiting the zoo in animal guise this Sunday, Noah's Ark Day, gains free entry and the chance to hop on a barge during the 75th birthday celebrations on October 7. The real animals had to move when they outgrew Moore Park, now the site of Sydney Girl's High. September 24, 1991. (Photo by Tim Clayton/Fairfax Media via Getty Images).
