Darn crappie are just fickle. Seems when they want to bite they do, and you can't force them because they'll stare at anything forever and not hit it. Good news is you probably have found a spot where it will get better as we approach spring possibly moving a bit further into the bay. Good job on not quitting n a spot where there are obviously some nice fish.
Spud one, spud two, if it went through, so will you!
