It's growing dark and your dry fly is getting very hard to see. But there's one good fish rising in that far seam.

Under these conditions, even setting the hook is difficult - but you won't get the chance until you get the drift right. And the odds of that are pretty slim if you can't see your fly.

Like a lot of others, I use Frog's Fanny (a white dessicant powder) to revive soaked flies, but it's also a great "highlighter."

Frogs Fanny normally works best when used sparingly. Under normal conditions, I blow away excess dust, returning the fly to its normal color. But when I'm after one more fish at dark, I go a different route.

I apply a small amount, work it in, and then apply an extra coat to the top of the fly. It typically won't float long (AK Best suggests leftover dessicant absorbs water and actually sinks the fly), but for a couple casts, the whitened top of the fly stands out like a beacon.

Cast, drift, bingo. See you at dark, Tom Chandler.
