About the only certainty, other than uncertainty, in fly fishing is that a fly won't catch fish if it stays in its box.
Fly-fishing is the most fun you can have standing up.
On the Firehole I caught thirty-six inches worth of trout - in six installments.
The fish is not so much your quarry as your partner.
I now believe that fishing is far more important than the fish.
...water that isn't fit for trout won't much longer be fit for us.
