A gentleman by the name of Levison Wood has taken it upon himself to walk up the Nile from its source all the way to the delta. No small feat, it spanned 3,750 miles, 7 countries and took 12 months. It would have been 4,250 miles had it not been for fighting in the Sudan that forced him to stop. Along for this epic journey was his trusty Leica camera. Check out his book on the journey called, Walking the Nile, the Channel 4 site of the TV program which is currently showing episodes on Sundays or the Facebook page.
