High on the Nile

New Zealander Cam McLeay has rafted some of the world's wildest rivers and he's the first to travel the entire length of the longest river on earth, the Nile - a feat never achieved by ancient Egyptian armies nor by intrepid 19th century British explorers. In following the Nile from lake Victoria to the Mediterranean, Cam McLeay proved that the river is 107 miles longer than the maps show and that a secondary source of the Nile lies in Rwanda. Ben Lowings caught up with Cam McLeay at the headquarters of his rafting business on the upper Nile in Uganda
