That’s awesome. I’ve only been on Luzon and sailed through the San Bernardino straits and seen all of those Visyan islands. I’ve never been to Mindanao but I’ve heard it’s beautiful.
Back in the 1980s Mindanao was safe for Americans to visit. Alas, that is no longer the case, because the Moros (Philippine Moslems) came under the influence of outside terrorist movements like Al Qaeda and ISIS, so they have expanded their rebellion against the Manila government to include Americans.
