Some parts of this book are really interesting and well done, and others, especially toward the end are so sloppy I wondered why Rosen put them in at all. Overall, a neat look at people who are living off the grid for one reason or another (though those with religious or privacy reasons get the sloppiest chapters). At the end, he writes a bit about the future of off-grid living, suggesting that more people will become interested in doing so because they are losing faith with big corporations and big government; he seems at first to really admire the concept of families and local communities taking care of each other. Then he recommends that the federal government start a big project of off-grid developments to encourage people to explore the lifestyle and make it more mainstream. Uh... what? I think he missed the point.
