There was a stop along the way at the Olback primary school in northern Arusha, Tanzania. There were hundreds of kids attending and we had a very cool interaction with them. They sang songs then groups of them grabbed us by the arms and led us to their desks. We chatted a little bit then I went to the blackboard and started writing arithmetic problems. They were very sharp and enthusiastic. It was fun. BTW-some of these kids walk over a mile to school each day.
