Is Chlo a male or a female name/alias? If you are a male I would actually suggest that you at least do parts of your travelling by train. Train travelling is really a way of meeting locals and of seeing parts of Africa that has no other connections to the rest of the world but the railway. When I travelled by train in South Africa, Mozambique, Botswana, Zimbabwe, Zambia, Tanzania and Kenya by train in 2001 I was the only "muzunga" ("white man"
on the trains Komatipoort-Maputo-Komatipoort, Livingstone-Kapiri Mposhi and Dar es Salaam-Mwanza respectively.
If you are female however I would not recommend you to travel alone at all.
