March 31, 2008 - April 3, 2008

Chapel Hill, Westwood, Memphis, Lawrence, and Springfield. This was during March Madness, and these places last multiple weeks.

March 10, 2008 - March 13, 2008

Quito, Sorong, Kampala, Kisangani, Libreville, and Singapore. Cities near the equator. One of my favorites.

March 3, 2008 - March 6, 2008

San Antonio, Chillicothe, Providence, and Rutland. I have no idea what these have in common. I wish I caught more of the cities on the globe this week to clue me in.
