He's the man without fear, and he has a new book: Rob Flickenger, now of Seattle, has revised his Building Wireless Community Networks for a second edition. I haven't seen the new version yet, but you can read a sample chapter and view the latest table of contents. I liked the first version for its excitement, practical advice, and its broad horizons. The second edition looks so far like more of the how-to and practical along with more about how wireless elements work.
