I'm reading this one right now. I've had it for years, but somehow it got lost in the shuffle, and only recently re-emerged. Lake Fishing With a Fly, by Ron Cordes and Randall Kaufmann, Frank Amato Publications, 1984. I'm also finding it to be informative. Filling in some of the holes in my knowledge, and turning on the lightbulbs in my head. Next on my lake fishing list is Tim's book.
