While Kristof continues to report from Africa, he's also putting energy into training the next generation of questioners. "A university student finds it much more interesting to read what another student is writing than a grizzled journalist," says Kristof, a decidedly ungrizzled 48. Thus, the "Win a Trip" contest was born. Kristof's first notion, to take students to Darfur, horrified the Times's lawyers. So he shifted to slightly safer spots. This summer's winners, Wen and a high school teacher from Chicago, accompanied Kristof as he wandered. "I just go out in the village and ask everybody what's going on, who's in the village, who's got an interesting story." And then he tells the world.
