I have worked and lived in many parts of Africa. Namibia, Angola, Zaire, Mozambique, Ethiopia, Sudan, Chad and Libya. Never got to Egypt. Not a chance in Hell a Caravan of "Enlightened Adventurers" in an Airstream could do this proposed trip in the World of today....it is not 1950.....Hemingways' Africa is gone. There is a wartime setting in all these countries, general lawlessness and a Cultural divide most have never experienced. Even in Zimbabwe today it would be a challenge.Keep the pink flamingos and blue beanies at home....sip your gin and tonic and plan your next Caravan across Columbia and Bolivia.
Yea, I know....pessemistic, grumpy, no adventure, old man!
