No, I have not read Angler Coast. It is a book that I am not familiar with. I have a rather large fly fishing and fly tying library, but as you know there are many books out there that all of us have not heard of or had the opportunity to read.
The most awesome collection of fly fishing and fly tying books I have ever seen is the one at Penn State University. I went there for a BS degree in the early 70's and spent many a day in the fly fishing section of the library.
