This picture was taken in January 2008 at the Kilimanjaro Christian Medical Center in Moshi , Tanzania . Abdullah Munish, the guy in the wheelchair, runs the wheelchair workshop at the hospital. Daniel, who is on crutches, runs the Mobility Care workshop in Usa River , Tanzania . We were walking back to Abdullah's workshop after eating lunch together. These guys are very good friends. They work on a number of wheelchair projects with us and have hosted multiple students at their workshops. They both came to MIT in February to speak to the wheelchair class.
