Seen dock owners put wood or wire around bottom of dock to water to stop dock shooting . Some even run out and cast lines with bobbers all around the dock to keep boats away . Harris Brake here in Arkansas . Some even have trap doors to fish through . I pulled up and used a long pole to reach the trap hole . Owner ran out and closed the door , told me I did not build that for you . Was tempted to slip in one night and sink heavy weighted rolls of netting to stop him from fishing it . .
