The local belief is that if you tie a stone to a tree at Crater Lake and make a wish, it will come true. If the wish does come true, you are supposed to come back and then leave an offering to the gods. We may have to come back one day. This trip has really been fun. There are 4 families of Americans who live and work in Indonesia who are on this trip. We also met a couple from Holland and there is a group from Switzerland on this trip. Truly an international gathering. The boat is very relaxing.
