Jolo is an Island, and it is also the Capitol City of the Province of Sulu.  Sulu is probably the most dangerous place that you can set foot in Mindanao.  It is one of the few places that I have yet to visit in Mindanao, but I will go there one of these days when the time is right.  I did shoot this photo of Jolo while flying over the City on my way to Tawi Tawi.
