Yeah, you're an outdoors person, fearless and all. So you want to go the rugged independent route? You want to go out on your own and snorkel without a guide or a boat? That's great. Jump in the Atlantic and swim. But if you're hankering for a guaranteed good time, get yourself to South Florida Diving Headquarters. They'll take you on a three-hour expedition in a glass-bottom boat about a quarter-mile off Pompano Beach where you can snorkel a natural reef and the 103-year-old shipwreck of the S.S. Copenhagen. You're sure to get up-close and personal with nurse sharks and to see all the colorful angel fish, moray eels, turtles, soft coral, fan coral, and sponges your heart desires. But like most good things, it will cost you -- $30 for the tour and another $10 for the gear if you don't have it ($15 for kids under 12). Or you can do just a glass-bottom boat tour for a quarter C-note. That's a small price to pay for uncovering the treasures of the sea.
