...in which we commemorate the 30th anniversary of Alfred Wainwright's passing by taking a virtual stroll to Innominate Tarn with archivist Chris Butterfield and long-time AW film-maker Richard Else. As we wander – through the history of the Pictorial Guides and AW's television career – we discuss what makes the Guides so unique; we talk about the emergence of an unlikely cult personality; we hear why the great fell-wanderer was almost certainly on the autistic spectrum; we trace AW's final steps onto his beloved Haystacks; and we pose the question: 'Was AW a genius?'
