(Cannon Beach, OR) -- The U.S. Coast Guard rescued a father and son who were stranded on rocks near Cannon Beach. On Sunday, 911 received a call about two people who were missing after going wave surfing. The father and son got caught in strong currents off Indian Beach. A Coast Guard helicopter crew found them clinging to a rock on the north end of the beach and they were hoisted into the helicopter. They didn't need medical care. Cannon Beach Fire says it was their third rescue in a week, and they're urging beachgoers to stay away from the surf zone when there's a hazardous beach statement issued.
