I met a chap from Wales on Sunday, who comes to the United States every quarter for two weeks. He very much wants to get into fly fishing, and asked me to recommend a good introductory book to fly fishing generally. I know Dave Hughes has written a book on basic fly fishing (which I have not read), but I am looking for additional recommendations from members that I can pass on to him.
Over in the UK, he will probably be fishing for trout on rivers, using a one-handed rod (not a spey rod). But he is looking for a general introductory book, not one limited just to trout fishing.
Any suggestions would be welcome.
