psu, i am almost certain it is single-hook. every available game warden is dispatched there in the spring, which leaves other areas wide open to snagging. i hear the mahoning river below berlin dam is quite vulnerable to snaggers in the spring because of this.
wolf, i remember back in the mid 70s, during the arab oil embargo, when guys were shoulder to shoulder on the ohio causeway bridge. some would put bar stools against the railing and spend countless hours there. one guy from cleveland had a net with at least a 12 foot handle to net fish. one night as he swung the net across the railing, a car came an spun the net and him around. never did see him again. we would fish on the rocks with raps and jigs and watch the circus above and down from us.
