Actually, I would normally rate this book a 4 but I thought the previous rating showing a 2 was too low. I found the book to be very helpful. Not being familar with Maine, VT, or NH, I was able to quicky determine not just where to fish but where not to fish. The book is targeted more toward fly fishermen (I am one of those) and it lists what hatches are on the stream. A familar fly fisherman knows roughly what month such hatches are around. I would highly recommend this book over a Maine Gazette map which will not give you the detailed directions to some popular fishing spots.
