Nairobi - The jeep bumps along a dusty track, its occupants peering out into the long grass, studded with the occasional Acacia tree, that carpets the open plain as far as the eye can see.
Scores of wildebeest, zebra and impala feed contentedly across the plain as the sun reaches the end of its long trek down the sky.
Suddenly a finger points and the jeep shudders to a halt. There, emerging from the grass, comes a solitary lioness.
