Used by both the U.S. Forest and Park Services, this manual explains how to plan, build, design, and maintain trails.

This is the classic, comprehensive manual on how to build a footpath to withstand the beating of 8 million boots a year (some hitting the ground 5 million times), to rest lightly on the land, to preserve the natural resources around it, and to allow a true backcountry experience-all at the same time. It is addressed to those who work on the Appalachian Trail-4,500 volunteers putting in a total of more than 185,000 hours a year-but is used by veteran and novice trail-builders around the world because of the success of the Appalachian Trail system. Illustrated with more than 50 photographs and 100 explanatory drawings, this manual includes design and construction specifications and lists of tools and U.S. suppliers.

Divided into three sections, Hope, Human and Wild profiles the efforts of three caring communities to preserve wilderness and reverse environmental devastation. They include the reforestation of McKibben's home territory, New York's Adirondack Mountains; solving traffic and pollution problems in the densely populated Curitiba, Brazil; and how the citizens of Kerala, India have demonstrated that quality of life doesn't depend on overconsumption of resources. This edition features a new introduction that revisits these places and explores how they've changed over the years.

The budget battles of recent years have amplified the warnings of demographic doomsayers who predicted that a wave of baby boomers would bleed America dry, bankrupting Social Security and Medicare as they faded into an impoverished old age. On the contrary, argues award-winning journalist Chris Farrell, we are instead on the verge of a broad, positive transformation of our economy and society. The old idea of "retirement"--a word that means withdrawal, describing a time when people gave up productive employment and shrank their activities--was a short-lived historical anomaly. Humans have always found meaning and motivation in work and community, Farrell notes, and the boomer generation, poised to live longer in better health than any before, is already discovering unretirement--extending their working lives with new careers, entrepreneurial ventures, and volunteer service. Their experience, wisdom--and importantly, their continued earnings--will enrich the American workplace, treasury, and our whole society in the decades to come. Unretirement not only explains this seismic change, now in its early stages, it provides key insights and practical advice for boomers about to navigate this exciting, but unsettled, new frontier, drawing on Chris Farrell's decades of covering personal finance and economics for Bloomsberg Businessweek and Marketplace Money. This will be an indispensable guide to the landscape of unretirement from one of America's most trusted experts.
