Talk about people who need a map. Two french tourists (Guillaume Combot and Enora Nedelec) are in the middle of a three-year hike from Cape Town, South Africa to Paris. They are now near Khartoum Sudan. Check out their web site here. (It is in French, but there is an english version, which looks like a machine translation.)
They must have access to computers as they are posting updates and photos. There are also some videos. There is a fascinating one showing how Guillaume cut pieces from a water bottle to reinforce his crumbling sneakers.
I hope they write a book or make a documentary film of this adventure. In addition to all the other adventures they are having, I am curious how they are navigating. Do they use a GPS? Are they using road maps? I know from experience that good road maps are hard to come by and are expensive in many African countries. This is an adventure I definitely want to keep an eye on.
