Greg French might best be known as the man who wrote the first accurate and comprehensive Tasmanian guide book, but there is much more to Greg than just the man behind the maps. Greg is the author of four published books with two more on the way. His most popular book, Frog Call, is brilliantly written and received raving reviews. Now the Tasmanian local is bringing his extensive knowledge about fish biology and hatcheries into a book about an area of concern in Yellowstone National Park.
