That is a good point he makes here. I have in the past gotten really nervous when I couldn't see ym fly in the water. As I began initially fishing exclusively dry flies and big bright streamer patterns.
One night I was fishing and they started feeding on a hatch just as the light started to fade. I had no idea where my fly really was but I tried to match the current speed with my eyes and follow fromt he splash as it touched down. Believe it or not... (I couldn't!) I caught three or four just like that.
Instead of watching the fish I was watching for a rise in the general area I figured my fly was and I was only wrong a handful of times as I turned a failed attempt at hooking up into a back cast. A replaced the fly where I had last left it.
Oh good times!!! The joy is seeping into my tired expression as I type about it. LOL!

Found this to be an interesting video on site fishing
Eventually, all things merge into one, and a river runs through it. The river was
cut by the world's great flood and runs over rocks from the basement of time.
On some of the rocks are timeless raindrops. Under the rocks are the words,
and some of the words are theirs.
