JUBA — Close calls with crocodiles and a brutal civil war have not deterred a British man from attempting to walk the length of the Nile River. The yearlong, 4,250 mile journey along the world’s longest river will see the former British army captain pass through seven countries. After four months trekking through Rwanda, Tanzania and Uganda, Levinson Wood is now in South Sudan, a country with little infrastructure that has been destabilized by months of fighting. The 31-year-old Wood said it took three years to plan the walk from Rwanda to Egypt. Wood said he faces many dangers on the walk from both man and beast but he noted that past explorers didn’t have the luxury of a satellite phone or Google maps. — AP
