For the past three summers, Evergreen resident Nancy Knight has traveled to a remote area of Sierra Leone, where she has worked with blind students at a school in the impoverished country.
As a teacher of visually impaired students at Heritage High School in Littleton, Knight said she has had many memorable experiences. However, working with students in a remote African village has been incredibly rewarding, she said.
"It's a huge gift to me," she said. "We feel like we are really making a difference."
