One of my favorite weekend morning rituals (when not actually fishing) is to grab a cup of coffee at the gas station in downtown Cherry Valley and head over to the Stae St bridge and the RR bridge and observe. I could stare down at the river for hours. My wife thinks I'm nuts, as probably do the joggers, bikers, etc that pass by while I'm zoned out staring at the water.
Anyway, when I see a carp or two cruising around I'm surprised if I DON'T see a smallie or two trailing. They also trail the suckers. The smallies range in size from dinks to good sized fish in the teens. I've never seen a huge smallie doing it, but you rarely see a huge smallie from these bridges anyway.
As far as what do do if you catch one, I think Eric has an excellent point. Dead fish on the banks are terrible PR for our sport. Ever have your dog roll in a ripe dead fish? That does NOT smell like Teen Spirit.
