In the story of Noah's Ark, a portion of the living world finds sanctuary in a pinch. I thought about that as our rig bounced down the steep track into Ngorongoro Crater, Tanzania.
The tunnel leads from the dungeons to the harbor.
At the end of the tunnel hangs an ominous sign: “Door of no return.”
Through this door human beings were marched from the bowels of the castle to the holds of slave ships. The transition from a stone to a wooden prison offered the captives one last gaze to the African sun. They would not see it, their families, or their homes again.
