Hmmm.. How does the Marburg get to the exclave of Cabinda without getting to the 'Democratic' Congo?? I suppose it's quite plausible, but still..

for larger scale map with roads. You'll see that there are roads that connect Uige via DRC. Since both Uige and Cabinda have coffee plantations i assume that there is a fair amount of contact between the two. Although I would also be worried about a coastal freighter between Luanda's port and Cabinda. I don't know where in Cabinda the cases are.
