We arrived in Namibia. The road from Maun in Botswana to Gobabis in Namibia were perfect and we drove an averag of 110km/h. There were virtually now villages as Botswana and Namibia are very sparsely populated - only about 2 inhabitants per sqm.
I forgot to mention that Botswana is the african country with the highest AIDS infection rate. A third of the population is infected. The disease lowerede the life expectancy from 60 to only 31 years. Similar figures are found in pretty all countries we travelled through. I don't think that we get the scale of this disaster in Europe.
