Mike, I am glad your courageous Dad is alright. This is an awful thing to happen. Rip Tides are nothing to sneeze at. They should have had a warning flag if there were lifeguards. When we have a warning here they alert everyone. Still a few will not heed the warning and venture out resulting in drownings every year. A Rip Tide will knock even a heavy person off of their feet and take them out.
This is a sad tragedy.
