I mostly fish Barren and what little night fishing I do anymore is always under a bridge. It hasn't always been as we had tried brush as well as in-take water towers that always seemed to attract more night time fisherman than it did fish. We started fishing bridge pilings with a little more success than the other spots and yes your still gonna have those nights that are stinkers, its called fishing. We tie something that floats, marker buoy, to a line and motor around the piling till you catch up with your float. before tying off, put two or three fenders between your boat and the piling. We use white lights as well as the green tubes and try to stagger the hooks till we can hone in on their feeding zone. Not exactly sure why the pilings out produce the other areas we fish during the day but the one thing the bridge has that the others don't is current. On Barren it always seemed to me that the days that the Corps is pulling the lake down were the days we did well and the harder they pulled it the better.
Everything is possible. The impossible just takes longer!
