Watching the world go by, sat on a bench, I saw this life guard on Filey beach as he drove the few hundred yards up the beach to move these flags further out to sea as the tide was going out. It must be a pretty boring job at times, especially on a day like this where there wasn’t anyone swimming in the sea. I am pretty certain that these flags indicate that it is safe to swim in the area of beach between them (as there was another one down the beach to my right as I took this picture).
