Fripp Island Sea Rescue volunteers rescued two teenage boys stranded on a sandbar near Hunting Island as the tide was coming in Saturday afternoon.
The boys, vacationing from Asheville, N.C., had walked about a half-mile offshore during an exceptionally low tide, volunteer rescuer Paul Field said.
A woman on the beach spotted the 15- and 16-year-old and called for help. Fripp Island rescuers picked up the boys in a 22-foot boat at about 3 p.m., Field said.
Field said recent low tides are like "an open invitation" for beachgoers to walk out on sandbars but strong tides and deep holes have caused drownings in the past.
