I've never done any dock shooting at PK. Usually the water is so clear it's tough to get the crappie to bite even when you can find them. The normal method for me is a deep water shady dock and minnows. For every crappie I catch I'll catch a whole bunch of big perch.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
