In another interesting update, the Philippines will possibly grant access to military facilities in the Batanes Province, which is the northern tip of the Philippines. According to Wikipedia, the Province of Batanes is in the northernmost province in the Philippines, and is about 101 miles North of the Luzon mainland. This is a mountainous and hilly set of islands, but the main island of Batan is more level.
