I believe that colour is more important in still water than in rivers etc. That has been proven to me by my own experiences. In all cases it is even more important to mimic the movement of the adults as you see them moving on the water. In still water I would locate a school of fish patroling a section of the bank where Caddis were bouncing about, lay my fly out after they went by and then when they were almost back I would twitch the dry and invariably hook or miss a fish. I have taken more fish in the rivers dead drifting a Caddis through the riffles that dead drifting on a lake.
Each smallest act of kindness - even just words of hope when they are needed, the remembrance of a birthday, a compliment that engenders a smile - reverberates across great distances and spans of time, affecting lives unknown to the one whose generous spirit was the source of this good echo, because kindness is passed on and grows each time it's passed, until a simple courtesy becomes an act of selfless courage years later and far away.
