Presenting a fly to a tailing redfish 40 feet away when a mass of protruding grass separates you and your target is not easy. First, figure out which way the fish is moving and aim 2 feet ahead of its course. Your line will likely land across the grass tops, and your fly will get stuck on the grass above the surface. Next, instead of trying to strip the fly, wiggle the line with your wrist when the fish is close. The fly may plop into the water and get hit. If not, the wiggling grass will draw the red's attention, and it'll strike the dangling crab.
