Took the family in June and didn't get much. Went back to the same lake in July and fished for four hours with only a few and then found a pocket and caught 15 good ones in 20 minutes and went home. Took my boy out to a different lake in August and a similar story - had one keeper in five hours and then caught about 50 (35 keepers) from one spot in an hour. In both of the last two they were still biting good when we left . For whatever reason they seem to be more concentrated than normal.
