i have actually looked at this before. it has proven to "work" so far. i have caught fish when it says the fishing is good, i have also caught fish when it says it is not good. the difference seems to be in activity. the fish seem much more aggresive when the weather channel tells them to be. how they mass communicate, ill never know, but it seems to be helpful so far. i guess its just like the deer crossing signs on the highway, how they train those deer to cross right there just blows my mind.
