We haven't been to the coast at all this year JHW. Our neighbours-with-children have, but told us the beaches were absolutely jam-packed with tourists and holiday-makers. We're being very careful not to expose ourselves to Covid at the moment, so haven't risked it. In spite of having two jabs each, we decided to 'play it safe' for now.
Most of our beaches here have rules about not allowing dogs on them. But dog-owners do let their pets run on the sands and splash in the sea etc (which I can understand I suppose) However, neighbours said there was dog mess all over the place, and their children accidentally walked in it! Yuk.
