Big Zig, both of the areas you suggested should have fish. The key will be making them bite. After a cold front the fish seem to get lock jaw, so any finesse tactics you have should work. Hair jigs, marabou, anything small should help you catch fish. The other key thing to your locations will be structure! Find brush, tall weeds,etc. and the fish should be close. As you know nothing is guaranteed Good luck and tightlines.
