Group work

I'm not sure what is happening here. About a dozen people, all dressed in white, were paddling at the sea's edge in Folkestone. After a while some went in deeper. It was clearly organised, but I don't know anything about the significance. Otherwise, it was good to get out and get some sea air. The cafe at Dungeness was shut - no big surprise - but the sun came out and the rain held off as I went along the coast.
