Thanks Southern boy, I know exactly the reed bed you speak of...has a big open area right in the middle. I actually pulled the boat out after cleaning fish this morning but, now I know.
Jonas, I landed one of those monsters back beyond the railroad tressle, beyond the second bridge...man alive I thought I had the hoss of hosses on the line...big [censored] turtle was as big as my net.
Good luck with Calaveras all I am out of there until Spring.
