I fished Horseshoe right above Boyd there at the inlet today causgth aroudn 25 crappie kept 5 a slew of small largemouths a sucker some and some tiny perch. Sounds like you were jsut at the wrong spot. Mostly on jigs a few on worms.
They were biting good for me I outfished the other 7 people there combined by a lot. The techinque was pulling a 1/8 chartuese jig real slow throught the water. Most the time it would just get heavy and I wouldnt even really feel a bite but I got hits almost every other cast. THe little bass were nailing it however.
