Fly Tying, an addiction in learning, Love it.

I look into... my fly box, and think about all the elements I should consider in choosing the perfect fly: water temperature, what stage of development the bugs are in, what the fish are eating right now. Then I remember what a guide told me: 'Ninety percent of what a trout eats is brown and fuzzy and about five-eighths of an inch long.' - Allison Moir.
