Jennilea and her amazing GoPro camera/video recorder, giving a pretty good idea of what it's like to bicycle in the Sudan, although this photo doesn't adequately convey the fact that it was hotter than the surface of Venus out there.  That's me in the background, actually turning to steam inside my bike shirt. 

Because some of the roads were paved and some were not, most riders brought different tires for different surfaces.  For example, for Ethiopia, I used tires made of small children.
