Miami mayhem got you feeling like a wreck? Then why not take a flying leap? We've got just the place: Fowey Rocks, about six miles southeast of the southern tip of Key Biscayne on the Gulf Stream's edge. A lighthouse atop a 110-foot iron frame tower, built by U.S. soldiers in 1878, helps cargo ship captains avoid the shallow spot. Unfortunately the beacon wasn't around when the British battleship H.M.S. Fowey scraped bottom there in 1748 and sank just to the south. But if you can find a pleasure boat or a willing sailor, head straight for the submerged rocks; it's easy to drop anchor there. Once you arrive you'll find a twenty-foot-tall platform, which once served as an access dock for the lighthouse keeper. Dive in, drift over to the metal ladder attached to the platform, and climb up. At the summit you can put your family, your job, and your world into perspective. You think your life is hectic? Gaze eastward over the water and contemplate the Mexican sailors whose tanker was torpedoed by a German U-boat near here during World War II. Then put your worries behind you, leap into the void, and scream as loud as you want on the way down. (Don't worry, the water is deep enough.)
