Entertainer Sonya Mendez leaves today for Addis Ababa, Ethiopia, to participate in another round of Rotary Polio Plus immunizations and plans to revisit Jilo Ager, the village where she and colleagues last year promised to drill a "Well of Hope." The well, she said, will mean that "children will not have to wake up at 3 a.m. every morning to walk a three-hour roundtrip to fetch water from a dirty river."

Last year, Mendez led a fundraising campaign for the project that now has nonprofit status. (You can donate at www.thewellofhopefoundation.org.) Plus, $1 from each sale of Mendez's "Back to the Islands" CD goes to the project.

She hopes to get Hawai'i performers to record a "We Are the World"-style song that she is co-writing with Bryan Kessler and Tim Bowden as a prelude to a "Concert for the Well of Hope" in 2008.
