Tomoko Tamagawa, 23, and Kelley Sterle, 22, are spending three months in Yosemite National Park as interns this summer, teaching visitors about the history of transportation in Yosemite and the use of alternative technology in transportation as well as about the natural, cultural, and historical resources in Yosemite National Park. They are participating in the Proud Partner Transportation Interpreter Program, which is made possible through a partnership between the National Park Foundation, the National Park Service, the Student Conservation Association, and the Ford Motor Company. https://www.nps.gov/yose/learn/news/sca2007.htm
