Book excerpt: The second book in the Immersion Travel USA series offers a one-of-a-kind examination of volunteer immersion opportunities throughout the US. Volunteer immersion means grounding oneself completely in the place, the tasks, and the people you meet along the way, while keeping your own goals in mind. Kayne profiles over 200 volunteer programs throughout the U.S., highlighting the personal stories of volunteers, and offering essential logistical information on the programs. Volunteer Vacations includes trips appropriate for families, children, teens, and senior citizens, and profiles opportunities over a wide range of categories, including community outreach, wildlife conservancy, environmental advocacy, national parks, education groups, and scientific research.
