I'd say look everywhere. If I'm not finding fish I try something different. It's all process of elimination. Look for patterns in where and when you see the fish. Just last week we got out and I figured I'd cruise the shorelines thinking they'd be up sunning themselves. Didnt' see anything. Finally found them out in the middle on a hump with just a few weeds. If the weeds got thicker, they weren't there. If the bottom turned to gravel, no carp. As the day got later they started moving shallow.
