It appears the only place to get Harley's latest book is through the Federation of Flyfishers and is titled as follows:
His recently published book, offered as compact disk by the Federation of Fly Fishers Hunt?Don?t Pray?for Fish: Techniques and Strategies for Fly Fishing from a Drift Boat is a culmination of almost 60 years of guiding and fly-fishing experience gained from fishing all over the United States and parts of Canada and Mexico.

"There will be days when the fishing is better than one's most optimistic forecast, others when it is far worse. Either is a gain over just staying home."
