Wow! I am in awe of you catching crappie at Possum Kingdom. Black Crappie as well, since the state does not list Black crappie as a species in that lake. I have fished PK since 2011 fairly hard and have not caught a crappie there since spring 2011. I've even tried minnows. I always catch fish but they are sand bass and stripers.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
