Joe Humphreys has updated this classic volume with an all-new section packed with informative text, great photos, and useful line drawings by the original book's illustrator, George Lavanish. The new section of this second edition covers many of the same topics as the original book, but all of Humphrey's tips and anecdotes are brand new. For instance, in the chapter titled 'Water Temperatures', Humphreys cites recent studies to explain the different ways trout feed in response to various combinations of water temperature conditioning and pH levels. This second edition of Joe Humphrey's Trout Tactics should definitely be at the top of every trout fisherman's reading list.
