The Coast Guard is searching for two teen-age brothers from the Tulare County town of Dinuba who were swept away by a riptide while playing in the surf north of Morro Bay. The boys, ages 13 and 17, disappeared in 55-degree waters while their father watched from the beach, Morro Bay police said. "Moments later their Boogie-Board washed ashore without the boys," Officer Manuel Silva said. Two Coast Guard cutters and a helicopter were searching 10 miles of coastline from Point Buchon to Cayucos Point, according to Petty Officer Elizabeth Neely. The name of the family was not released.
