American Students Build Schools in Senegal Annika Hammerschlag GUEDJ MARTIN, SENEGAL - The roar of power drills fills the air in the village of Guedj Martin, a typically quiet community of 2,000 people located some 100 kilometers (62 miles) from the Senegalese capital of Dakar. It's an unusual sound to behold in a village with no electricity, but the noise is a welcome disruption. A group of 13 students and five chaperones from Lich-Wilmerding High School in San Francisco has spent the last two weeks building a primary school that will serve Guedj Martin and its neighboring villages. They're covered in dirt, dust and sweat, and blue and yellow paint is splattered on their clothes and shoes. .
