I've fished drys both ways ... come to think of it, wets & nymphs, too! All depends on circumstances and the lay of the land ... (eh, stream).

Now I like to fish streamers caddy-woppis, i.e., across and down stream, let the current take it down along the bank and when the slack runs out it tracks from the side to center stream. Hey, it works for me!

MY original fly fishing mentor was a die in the wool dry fly fisherman. Taught me very much. However, I've caught many more fish subsurface (I can just see him turning in his grave!) ~
