Coming here ranks as my most unusual arrival into a country in my life so far. The boat we'd taken from the Malaysian side arrived into Tarakan. A typical border town, with zero to recommend it. It berthed not against the pier but adjacent to another boat, with the only door on the side facing the open ocean. Fully laden with all our belongings we climbed around one slender hull, then delicately across a second before hauling ourselves up on to the rustiest, most derelict pier in southeast Asia. Welcome to Indonesia.
