To true Jamie, my fiancees family (Bukidnon) always advise against us going much further west than where they live, it doesnt bother me but i always heed there advice.
Gen San, Dapitan, Iligan and Ozamiz are meant to be OK.
Cotabato, Pagadian, Zambo and the rest of the Sulu peninsular are somewhat precarious according to a number of sources.
