The landscape is quickly changing now from desert to savannah. Yesterday we spent the time between (huge) rocks and (lots of) sand, today the dominating colors are green (grass) and red (the sand under the grass). Driving is much easier in the savannah, but navigation is more complex because of the myriads of faint tracks criss-crossing the landscape. You don’t know if the chosen track is going in the right direction until you have driven a few kilometers. In addition there are many dry riverbeds which are hard to cross. Plus thousands of cows, donkeys, and camels you should not hit either.
