For me i try to do what they all said above as well. But it is a different day so go try and maybe the fish are doing the same maybe they are not. Absolutely no way of knowing without going. Then just look for the fish .
I don't just use CDC but I try and talk to everyone I can at the bait store, and at the ramp who looks like a crappie fisherman. For my money I go wherever I hear about the bite being the hottest. When gas is this high and time is limited I've got to find out where they're biting before I even put the boat in the drink.
