The drag is the dry fly man's greatest enemy and there are several kinds. There is the drag caused by taking in slack too fast; there is drag imparted to the fly by the wind catching line or leader and worse than all is the drag caused by the fly being near the bank in rather slow water and the line being farther out in the stream where the full force of the current acts on it. The first can be avoided by a little care; the second is never serious except on the windiest day when dry fly fishing is both unpleasant and unprofitable. The drag of the current is minimized by casting so that there is an upstream belly in the line or by straight ahead casting to avoid getting the line in fast water.
