Tambo

Time you got around to sponsoring a child
The Tambo, which rises in the Vilcanota knot of mountains south of Cuzco, is a torrential stream valueless for commercial purposes. The banks of the Ucayali for 500 miles (800 kilometers) up are low, and in the rainy season extensively inundated.
Tambo is also a shire in Queensland, Australia.
