Query: Tree Huggers Unite

In a word - boring. In two? Boring and dull. Not particularily interesting, not particularily insightful. Blah, blah, blah - it never seems to end. My friend's mother must have been high on crack to recommend this to me. Several hours of my life I'll never get back. I'm a bright guy, PhD, well read, enjoy camping and the outdoors - not as shallow as this review might suggest - but honestly, this book [stink].
