Africa keeps some secrets -- wild, private subtleties -- that it would rather you not know.
You may see a lion here, like I did. The continent, in general, is glad. Spot a leopard or catch a cheetah out of the corner of your eye, and all is well. Africa beams.
But what it knows -- and doesn't explain -- is that none of these are its king. On a recent trip to Zambia and South Africa, I stumbled onto the truth. The real wilderness royalty here is not a ferocious Big Five animal. It is water. Water from a river.
Livingstone, Zambia, where my wife and I spent most of a week, has this in spades. The Zambezi River, wide and strong near the lodge where we stayed, is Africa's fourth largest after the Nile, Zaire and Niger. It quenches the thirst of hippos, elephants and squadrons of exotic birds before exploding into spray for the 300-foot bungee-jump of a drop at Victoria Falls on the Zimbabwe border.
The local name for the falls, Mosi-oa-Tunya, means literally, "the smoke that thunders," so Kathy and I arrived expecting a locomotive of sound. What we got was a roar but one that is eerie, echoing, like an animal at night. Because we were there at the start of the rains, the flow was elegant, not loud. The rocks of the gorge displayed chutes of water that rippled and unrolled like scarves.
For a game drive in Mosi-oa-Tunya National Park, we hired a guide who introduced himself as Chesmore Zulu. "Look," he said as we passed through the entrance gate. Posted there is a gilt-framed photograph of a chubby man with an air of sympathetic understanding. It is His Excellency Mr. Rupiah Bwezani Banda, president of the Republic of Zambia, which has been an independent democracy since 1964.
We discovered a few shy zebras deep in the park and, eventually, a herd of sand-colored giraffes. Zulu mumbled as he drove. In Zambia, he claimed, it is legal to smoke anywhere "except in a bank." Kathy and I traded glances. Was this a lead-in to Zulu lighting up in the car?
When we passed some huts that looked like they had been systematically wrecked using bulldozers and steel balls, Zulu shook his head with disdain. "Elephants," he said simply.
