First point: great photo! Have you ever braved those rapids? How did it go?

Second point: often, dear scribe, you put some evidence behind your claims and cite sources like magazines or newspapers or the opinions of experts. I am missing those views when I read of your new approach to catching fish. Where does it say that "stealth" will help you reel them in? Can the fish really hear you or see you? Sure, if you fall in the water, they'll get spooked, but those TV show fishermen are all loud mouths and they are up to their ears in lunkers.

I wonder how many of these things are myths and how many are actually real.

Sure, it makes some kind of sense that fish are hungry in the morning, but why? Are they, like people, just waking up? Or have they been splashing around all night working up an appetite?

Is there a book or something debunks some of these potential wives tales?

Drew,

any number of books you can read on fishing for trout will tell you that fish are more active and eating when the air is cooler which in turn means in the morning and evening hours.
As far as stealth goes you dont have to be overly quiet unless there has been alot fishing action in the area which will intrun mean the fish that are there will be more skidish and take off at any sound or even the vibrations of stepping on a rock attempting to get closer to a nice deep pool.
