I personally wouldn't suggest any country over another...
Ghana primarily cause it's Anglophone...
Nigeria can be tricky, so if your running through say Lagos... make sure you got a strong team who knows the ares... corruption runs rampant...
Nairobi is beautiful... so no worries there...
you know? It just depends really... on the person... their perspective... their game (yup... i said it)... their heart... all these things combined... hell there are some blacks who still say Jamaicans aren't black so... foolishness is just foolishness...
