I look for older docks, most of the time, but will pick a cove or area and fish most every dock in that area. When I catch fish there I will mentally make note of it, and fish similar type of docks. The thing about dock fishing is you just never know till ya fish it. I will shoot an area 5-7 times if the fish is there they will hit it on the first or second time most of the time. If it is a dock I have caught on before I will spend a little more time before I give up and go to the next one. Shoot pontoon boats, they love them too!!!
