Yep, they will bunch up at first. But, they have been in there for 2 days now. So, they will start spreading out some about now. I'd start around ramp C, like Noah suggested. If that doesn't work well, I'd also head over to ramp A. Maybe they dumped some in there too.
BTW, I cast n' retrieve a large brass colored Little Cleo spoon/wobbler...very slowly and deep along the bottom contour. I'd also try Lemon Lime Power Eggs OFF the bottom too.
