The boys can’t swim and have never had any scuba training...monumental undertaking to think they can get them out that way! The cave also has passages that only one person at a time can squeeze through...talk about boys who would probably lose it under those claustrophobic conditions, wow. Waiting until the rainy season ends over there takes them to October, No thoughts I have of equipment to help those poor boys and I know there are people with a lot more knowledge of cave diving then me.
