See WWII Ruins
WIth a local map and transportation, you can head to the old airport. It's just a dirt strip, but there are some old relics from World War II scattered around the area. Drive down the runway and keep your eyes open along the sides for planes. I saw at least two fighters (can't remember if US or Japanese). Also, there are a few rusting antiaircraft batteries here as well. Quite interesting to see.
