As a young man with a compelling interest in the great outdoors and the natural world Allister ('Ashie') Brebner spent his precious weekends in the 1950s and early '60s as a pioneer of the emerging Scottish bothying and mountaineering scene, and was one of the builders of the famed Secret Howff on Bheinn a' Bhuird in the Cairngorms. At the start of the 1960s he threw in his steady, well-paid job as a factory worker and, with another companion who did the same, started as a pioneer of mountain and nature guiding in the Scottish Highlands. Here is the unique story of a working man whose odyssey took him from the tenements and factory work of Aberdeen to the mountains and islands of the Highlands, their people and their wildlife.
