That was always my opinion too until last year!!! Don't know what it is about the lake we frequent but last year we slayed them from 1 till dark. Don't get me wrong I caught fish in the mornings too but not the numbers we did in the afternoon. Now this is the same lake that 2 years ago my wife and I caught 27 in a little over an hour at 1230 on July 1 at 90+ degrees. We were only fishing 7 ft. water near a breakwall using minnows. I can say I had never done that before!!
