"If you are pan fishing you may want to take or make some anchors. "

For some reason that triggers a memory that makes me think that they don't use normal anchors down there. I think because the bottom is just layers and layers of silt that they use coffey cans with cement in them to help pull the anchors up. some anchors would sink real far and/ or have some sort of lip on them to cause extra resistance. Also my mind is a little cloudy because my last trip there was like 8 years ago, so that may be something completey random and wrong, but for some reason i think that is correct at least somewhat.
