I use to hunt the ohio down from Cinci. I don't think you can be in a boat under power. We always went to a field or point on the river and set up a temp blind. Got a few but they were far between. Going to Arkansas for opening day on the 18th of Nov. Guided tour. Got lucky when a spot opened up from some friends that go every year. Right on the flyway. They limited out in 1.5hrs last year. Boy does that make your $/hr hunting ratio go up.
