I just finished reading "the Wild Trees" by Richard Preston. It is an amazing read focused on the search for the tallest trees in the world and the organisms that grow in their canopies. The main characters are Steve Sillett and Michael Taylor, two of the foremost experts in this field. The book is amazing and inspiring. http://www.amazon.com/Wild-Trees-Story-Passion-Daring/dp/0812975596 Here is michael's website... http://www.landmarktrees.net/ Read this book!
