My first visit to South Africa came in the 1970s at the height of apartheid. As a young and somewhat idealistic professor on the Semester at Sea program, when the ship docked I was shocked to see “coloured only” signage echoing the racist attitudes and policies there. As was true at every port, after the bow lines were tied off, a group of customs and government officials came on board to review all the paperwork and passports before clearing the passengers to disembark.
