On the island of Halmahera, there is an airfield just to the north of Kao.  At the north end of the airfield there are about 4 disabled Japanese WW II anti aircraft guns.  (notice the fragmented barrel end) While at Kao I was recovering from a nasty flu but made myself get out of bed and find these guns. It was so damn hot here I couldn't believe it.  (can you see the sweat on my forehead?)
