Thanks for the reply Bill. I will try to get a better picture tomorrow, I have pulled most out already and the pic I took was after a day drying. I can find a few pieces yet in the water and will attempt to get a closer up with my camera not my phone. It doesnt appear to be attached, if it is pulls very easily. It was very thick in some spots and was all I could do to pull the loaded rake. Of course once out of the water and dry the weight is all but gone. I will lay a wet piece against something light colored to show more detail.
