Also under tactics is a genuine and still-useful classic: A Modern Dry-Fly Code by Vincent Marinaro (288 pp.; 1997 reprint of 1950 first edition. Illustrated. Published by The Lyons Press. Hardcover, $35). Most of the foundations of modern dry-fly methods are in this book, which the late Marinaro derived by careful study and fishing along Letort Spring Run near his Pennsylvania home.
