“A comprehensive study of fishing points of interest”.  The information contained in here covers the area from the Lake Fork Spillway and north along Big Caney Creek past Hwy 154 Bridge and as far north as Big Hurley Pone and Smith and Taylor Branch.  This also includes a navigation chip built specifically for Humminbird GPS Units which contains the coordinates for all the locations talked about in the book. It allows the reader to learn the lake by reading and then traveling to actual site location visits by means of their GPS units.  It’s a new way to learn Lake Fork.
