I am with "Buddy" on this. I go when I can and do not pay much attention to the "old saying", but, it would be interesting to keep notes and see if your "not so good catching" days fall on the days that the "old saying" states are not good fishing days.
I do know of some that will not fish on the days that the wind is out of the East, but, I will fish any day that I can...

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
