hey Tim L
it depends on where in Zamboanga Del Norte you are at. Dipolog is the capital of Zamboanga. That area is not bad. the main thing is be far away from Marawi city as possible in Del Norte. Just don't flash wealth, don't go out at night, stay with groups of people in day time and etc. Just like my other post. Use common sense.
Also the government is going to issue warnings for the whole region for their liability stand point.
