Thanks for the recommendation, Ron. I finally found the book at Powell's in Portland and I really like it. I particularly like the explanation of how to measure a tree's height using a piece of stick that's the same length as the distance between your eye and your fist. I was just in Portland for a ukulele festival, and one of my ukuleles is exactly that length.
