Where there is no Coca-Cola
Bulawayo, Zimbabwe Gas stations throughout Africa, like everywhere else, display their prices in big bold numbers visible from far away. One in Uganda might say something like: PETROL 2310 DIESEL 1680 PARAFFIN 970 ("Petrol", o American readers, is the British word for gasoline. Paraffin is primarily used as cooking fuel, but is also used for lamps and fridges.) If you walk from Zambia to Zimbabwe, as I did a couple of days ago, you cross over a metal suspension bridge perched 111 metres above the Zambezi river gorge. From your right comes the constant thunder of Victoria Falls. To your left, a bungee-jumping booth stands on the edge of the bridge. If you look over that edge, you may see, far below, amid whitewater wrinkles, yellow Tonka-toy-sized river rafts, full of adrenalinized tourists about to brave 22 of the 24 rapids of the lower Zambezi gorge. (One of them is Grade Six, too violent to raft; and you don't raft the last rapid, because then you hit croc territory.) O
