I love to read and I love books and this title soared right into my Top 10. Within minutes of starting to read it, I had gained useful knowledge I could apply practically right away on my next hike outdoors. The first thing I learned about was inversion and found out how it was affecting the outdoors region near my home. Each page I learned something new to look for while in nature. One of the most purposeful books I've come across in 40 years.
