On my last trip to the library, I picked up a book that I had never seen or heard of but was spot on about a lot of truth about the essence fly fishing, and a lot of things we tend to forget.
The book is Simple Fly Fishing, Techniques for Tenkera and rod and reel, by Yvon Chouinard, Craig Mathews and Mauro
Mazzo. If you can get a copy , I hope you will enjoy it as much as I have. Be sure to read the introduction!
