Many Q drops mention other countries using two letters. Some of them mention "SA". Many of us have interpreted this as "Saudi Arabia".
Could it mean "South Africa"?
South Africa has a major geographical advantage with regards to container ship travel from the Indian Ocean into the Atlantic.
Especially if Suez Canal were to be inopperable.
Evergreen was trial run for how to efficiently re-route nautical shipping traffic?
I didn't see anything notable when I tried that. Besides, even if some dates lined up, it wouldn't change the fact that all of the drops were clearly talking about Saudi Arabia. I actively tried to force them to be about South Afrika, but all that did was break any sort of cohesion.
