Pocketguide to Western Hatches
Best Bug Identification Book!
This book is small enough to throw in your tackle bag and is a GREAT read any time on, off, or near the water. The photos of the actual insects and the imitations accompanying them are worth their weight in gold. One of the angler's biggest decisions is "what fly do I tie on?".... this book helps you make an educated decision before you even get to the river.
