"River Hippies & Mountain Men" is the second book in the '21st Century Mountain Man' trilogy from amateur adventurer Patrick Taylor. It is the follow-up to "Lost on Purpose" and continues the true story of his audacious change in lifestyle. Crossing the Rockies alone on foot in 2013 was an admirable mountaineering feat, but the author sorely lacked the backcountry savvy he needed to be a legitimate mountain man. To live like his heroes, he had to know more about horses and hunting and backcountry living, so he hired on with a local outfitter to live and work in the wilderness. It was a world completely removed from the life he left behind; he was surprised it still existed. This book chronicles the former tech exec's two-year apprenticeship as a stockman and backcountry packer in the Frank Church Wilderness in Idaho.
