"I think in an ideal world there would be more naked wild swimming in the UK. Not only would that mean we were a nation of liberal, nature-loving and adventurous people, less constrained by our prudish stereotype, it would also mean more swimming in wild areas, communing with water in the way nature intended.
Naked swimming, especially when done in the wild, is spiritual and exhilarating. It certainly is not a crime.”
