Penny, you are so right with the scuba..I have a friend of mine that does various islands from year to year in the spring. He has, on more than one occassion been misinformed about one aspect of a dive that he was doing. Thank god he is no novice or could have been in trouble. Some people out there are looking out for the money and not the people they are suppose to have in their care. I don't scuba but have felt unsafe only once on an excursion where we did a snorkel sail.
