Explorer and mountain biker Shannon Galpin brings cycling to Afghan women. The 2014 National Geographic Explorer believes bicycles are a vehicle for transformation in a society where this simple freedom and pleasure is denied to women and girls. This simple act, easily taken for granted in the West, provides them with a stronger voice so vital in what often appears like an insurmountable obstacle--positioning Afghan women in a place of greater equality. Lessons: 1. Simply doing something right can a powerful form of activism since it will inspire others to mirror you. 2. Hope and change prevail over fear. 3. Don’t take even the simplest things for granted.
