John Muir grew up in Wisconsin and studied at UW-Madison, just like me. But then he went on to change the world, which I haven't quite figured out yet. While he was helping America develop its environmental ethic, writing inspiring accounts of his wilderness adventures, and pushing for stewardship amongst state and national governments, he lived here, on a ranch in Martinez, California. The house is now the John Muir National Historic Site, open to the public for a glimpse of the sacred space Muir maintained for himself and his family. Wonderful for the Muir family and the National Parks Service to maintain the home as a public treasure.
