Contest 10: Sister Act

The concept of Sister Cities has been around since the end of World War II, when President Eisenhower wanted to foster greater cultural understanding among nations. A number of the pairings (not unlike some couples in arranged marriages) seem a little odd: Tempe, Ariz., and . . . Timbuktu, Mali, for example. Kathmandu, Nepal, and . . . Eugene, Ore.? Hmmm. Our own D.C. seems a little ambitious, with three sister cities: Bangkok, Beijing and Dakar, Senegal.

In the name of promoting even greater international harmony, we now invite you to pair any two cities that would go well together and explain why they make such a fitting duo.

Example: If a city in southern Tennessee got together with the capital of Burkina Faso, they could share a theme song titled "The Chattanooga-Ouagadougou Choo-Choo."

Results from Contest 8: Putting the geo in george w.

In Contest 8, we discovered that many of you are supremely qualified to serve as George W.'s foreign policy advisor, since you correctly matched the four world leaders we listed in our print edition with the countries they rule: Denmark, Uzbekistan, Moldova and Botswana. Congratulations to Juan Rodriguez of Lexington Park, Md. (who also figured out the acronym formed from the first letters of those nations). Perhaps we should have added two more countries, Ethiopia and Romania, to round out the message, since we named the leader of Macedonia, not Moldova, on the Web version of our contest. Among those who competed online, we award another coveted Travel mug to Linda Pardoe of Columbia.
