Not a folkie (although passionate about music), my late friend, Roger Deakin, whilst travelling round the country 'wild' swimming prior to writing his delightful book, 'Waterlog', had an ancient Citroen estate that, amongst other creature comforts, contained a library of his favourite books. When he slept in it at night he covered the whole car with an ex-military parachute. An amazing and wonderful man and a true and unpretentious eccentric.
