John Muir spoke, wrote, and lived the wilderness, including taking President Theodore Roosevelt on an overnight trip to the Yosemite Valley. This trip led to Roosevelt's signing into law a bill that placed Yosemite under federal control as a national park. Because of this and his founding of the Sierra Club, John Muir is credited as one of the key shapers of the modern environmental movement.
The biggest threat to America's forests - marijuana grows. Mentions marriage to Louie and their kids and shows them in front of their house, but no mention by name of Contra Costa or Martinez. Good bio of Muir and history of the environmental movement.
This book has very good information about John Muir. It is very detailed and tells about his whole life. It also talks about the places he traveled, things he accomplished, and things he didi to help preserve nature.
