A Polynesian voyaging canoe is on a four-year journey circumnavigating the Pacific Ocean, using only traditional methods of seafaring - so no GPS, no motor, no high tech sensors, but lots of sails and wind power. The canoe and its crew recently sailed down the California coast, meeting with indigenous communities along the way. KQED’s Katherine Monahan spoke with the crew about what they've learned from California and the people they’ve met here.
