The option is kept open, for sure. But I can't picture a scenario worth pursuing that would lead to Courland being the first to do so. As I noted much earlier, the Cape is south of the range of malaria (thanks to all that desert between Angola and the Cape).Very interesting, perhaps some Courlanders might be interested in the distance.
It feels a touch odd that I've given this timeline so much opportunity for sprawl, only to let most of them go. Maybe it's more convincing that way; maybe it's like a familiar life story.
