Just north of Mindanao on a tiny Island call “Nonoc Island.” There was a big nickel mine there. When I was there in ‘77, Mindanao was full of Maoists and commies. We were told it wasn’t a safe place to travel.
That’s still the case for western Mindanao. But on the eastern side (Davao and Davao City where both my GF and her friend the VP of the Philippines Sara Duterte are from), people can go their whole lives without encountering any sort of terroristic incident or serious crime.
Maybe a small chance I will end up there someday if things really deteriorate here. She still has a house there and relatives.
