My copy is in storage. I remember reading his book in 81 or 82.
I know this sounds crazy, but I seem to recall him saying that caddis flies were not considered an important fly to fly fishermen until the 70's?
If my memory is correct, isn't that astounding!?
Ibwas flyfishing in the early 70's and I admit the focus was on mayflies.
Would appreciate clarification on this from someone who has his book handy
