I have family down at Santee , South Carolina. They told me they have frisbee
sized gills there. You're right though, they call them shell crackers. Wow!
Also my friend at work lives on Knapp lake and his friends cottage had water come over the sea wall. When it receeded he found 3 11 1/2" gills laying in his yard. My
last blue gill tale is about a 13" gill found floating at iceout on a pond in SW Fort
Wayne. The fish was donated to a museum somewhere and the man who found
it photographed it. I will see if I can get a picture to post of it.
