Now if ya see flyers around a weedline,pallet or any other debris in the water then its deffinately worth pulling over and putting some baits in for a while and see if any life is around. If not only trolling but drifting or casting at the stuff with live bait while throwing some dead bait out to bring fish up from deeper water. Like said before,this usually happens during the summer months when the water temp is up but as long as its at least in the 70's,who knows ya might get lucky which is about 33% of this sport. Just one mans opinion of course.
