good American culture book

A few years ago, I created an American Culture class and used different sources, including the book American Ways, which I've recently started using again to tutor someone. The author has a lot of experience working with non-Americans and writes clearly about different aspects of our behavior and culture. When I first read it, I didn't find myself thinking, "this isn't true" or getting annoyed with his descriptions because he seems to give information that isn't biased. If he does make generalizations, he qualifies what he's saying. Of course, I can see people, such as the whiners who I've met in education, voicing complaints that he doesn't talk about *all* segments of society, but he admits to that. Which is why the book is informative and fair.
