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.
