I believe Tom McGuane is superb. Gierach can be good, but I think he may be disingenuous sometimes, (Imagine a fishing writer being disingenuous). Still, some of Gierach’s tales are classic.
Some Titles to consider:
The Year of the Angler and The Year of the Trout
by Steve Raymond *****
Royal Coachman by Paul Schullery ****
The Founding Fish by John McPhee *****
Does anyone have an opinion of , Trout Hunter, The Way of an Angler, by Rene Harrop?
