Les, we were looking for the Yams and Chestnuts in the National Park. I remember seeing one white fast flying UFO flying around the pedestal hut and guard box up along the path leading to the waterfall on our last day there. But did not manage to track it down. I must have make more than 10 trips up and down that trail alternating between the hut at the top and the small patch of sand around the bridge area nearer to the beginning of the path on that day.
Since the Mountain Resort is just across the other side of the mountain, we were juz trying our luck to see if the Yam/Chestnut can be found there too.
