“An old fishing adage says never have the sun or moon at your back. Most old rules are the best ones because they have been well tested, but where this one is concerned I guess I am an agnostic. Anyway I don’t believe it. I believe it to the extent that it’s dangerous to cast your shadow across a fish.”
I prefer to fish small creeks with the sun at my back. This way there is less glare and it is much easier to see the fish. I don’t find keeping my shadow off of the water to be much of a problem.
