Book excerpt: Here is a guide to the most revolutionary development in British angling for many years: fly-fishing for trout and grayling in the very centre of towns and cities throughout the United Kingdom. From Sheffield to South London, from Merthyr Tydfil to Edinburgh, this is the cutting edge of 21st century fishing. Nothing is more surreal yet exhilarating than casting a fly for iconic clean-water species in the historic surroundings of our most damaged riverscapes -- centres of post-industrial decay, but now also of rediscovery and regeneration. * fishing-focused profiles of 50 selected streams * interviews with local conservationists dedicated to restoring the urban rivers * local flies and emerging traditions, and * details of how to get involved and support this restoration work. This book guides readers towards relaxing, good-value fishing on their own doorsteps as a viable alternative to more costly (and carbon-intensive) destination angling: a positive lifestyle choice in challenging moral and economic times. No one author or publisher has yet attempted to bring this emerging trend of urban flyfishing into a single, epoch-making volume. **A donation from all sales goes to the Wild Trout Trust and the Grayling Society **
