When I was stationed at Barbers Pt. HI I had a friend who would go over to Kauai and hunt wild bore. He also picked up banana leaves and some kinda "K" wood, can't remember name. One year he had a roast in an imu he built out at White Plains beach (which is on Barbers Pt. near Coastie club) Anyway he had that pig in the ground with the good wood coals, banana leaves, covered the whole thing with hot rocks and even some siding/roofing. We got so blasted during the all night cooking/partying, good time and the pig was great! Another thing that guy did was dive for lobster, smaller than others but tasty!
