Fishing Tide Lines....

[PathfinderNI]

Have heard people talk about fishing tide lines....anyone have success doing it? Do you need to be in the vicinity of a bayou or cut coming out of the marsh or can it be just about anywhere? What do you look for when trying to find tide lines, different shades of water, eddies, bubbles, etc.? Any help is appreciated, I'm always trying to learn more to be more productive!
