I purchased this book many years ago, when I was just starting as a fly angler and it helped me immeasurably during my initial sojurns to the mountains of Wyoming. John Gierach's writing style is relaxed, informative, and entertaining as can be. He outlines the equipment (which essentially hasn't changed in the 20 something years that have passed since this book was published), the types of waters, the trout, their food, the weather, and anything else you can think of. As other reviewers have commented, this is an instructional book, which is GREAT, but it's also entertaining and filled with tpyical Gierachian anecdotes and stories. You'll be dreaming of mountain meadows and pine scented breeze as you read this little book and when the warm weather comes, reach for those hare's ear soft hackels, some midges, and your rod, and make tracks to the high country! This book is perfect for beginners, people wanting to learn more about the high country, or fans of John Gierach.
