were they relating to any kind of cover, or just sitting in a deep hole. I think alot of times, we get so hung on fishing brush and concrete, we forget to look at bottom features that they relate to sometimes. I fished 18 feet and less and didnt really think abt searching deep holes or ledges. if I recall the water temp was around 52 or 53. I did find abt 2o more piles, so it wasnt a total waste.
