 What's the greatest danger for beachgoers? Stinging jellyfish and sharks on the hunt are some ocean hazards that might typically worry beachgoers, but rip currents account for the most beach rescues every year. Six people drowned in rip currents over a recent two-day period in Florida. About 100 people drowned from rip currents along U.S. beaches each year. That's according to the U.S. Life Saving Association, and more than 80% of beach rescues annually involve rip currents. John Scott reporting.
