When you start trying to inject science and reasoning into fish movements, and their resultant activity level.....you're asking for trouble.
I'm not sure which bodys of water across the country have fish that adhere to the rules of things like "thermocline, PH, temperature avoidance levels" and so forth, but wherever those lakes/rivers are I've for sure never been there.
Going in totally ignorant it takes me about 2 1/2 - 3 days of hard fishing to put together a workable pattern that is even remotely reliable, and it never fails to defy the logic I've taken in by studying the "science" of fishing.
