the mention of Northern Rhodesia was really a Goof?
I'm not very convinced the mention of Northern Rhodesia and not Zambia was really a Goof.
Because many people continued using the old name during years (specially only 5 years after independence). Same happened in the 80s with names in Zimbabwe many people continued using Rhodesia and Salisbury (and not Harare).Apart of that, some former settlers used the old names in order to show their dislike with the changes and the "new order" .
