We saw two fly fishermen wading the river. They were having a great day but said they were challenged by the high water. We also encountered two fly fishermen being guided in classic Au Sable river boats. These long, narrow, flat-bottomed boats float downstream with the guide using oars in the rear of the boat to direct it. There is also a heavy chain that is dragged to help slow down the movement of the boat downstream. All were fully dressed in the obligatory Eddie Bauer fly fishing uniform. No levis and tennis shoes here. Even the boat riders were wearing dry suits that would enable them to leap in the water to go after their fish.
