Query: You'll read it and discover why you need it

I used to think that there was no strategy, per se, to fishing a lake--a big tub of water you trolled until you got an arbitrary hit.This book takes an almost forensic view of a lake's features--water layers, vegetation, etc.--and shows how to read them and catch fish. It's much more detailed than I expected and I came away with a real sense of how to find trout as quickly as possible.
