Grace held out her hand to me, and together we walked over to the man standing at the foot of a massive baobab tree. As the dust settled, the orange glow slipped behind the faraway hills, leaving us with maybe two hours before dark. The baobab towered over the forest, its limbs glowing in the dying light of day, and the man watched our approach with as much interest as a buffalo showed a pair of tiny ox-peckers.
