Christopher Nyerges, co-founder of the School of Self-reliance, has led wild food walks for thousands of students since 1974. He has authored 10 books on wild foods, survival, and self-reliance, and thousands of newspaper and magazine articles. He continues to teach where he lives in Los Angeles County, California. Zoologist Jim Kavanagh has made a career out of introducing novices to plants, animals, the sciences and world cultures. In addition to creating over 500 simplified nature guides, he has also authored guides to languages, cities and outdoor skills. An avid traveler and backpacker, Kavanagh's path has taken him around the world to many remote destinations including the upper Amazon, Africa, Australia, and the Arctic Circle (and this is just the As). He is also the author of a series of state-specific guides to common species and natural attractions and a children's book on evolution.
