Observation is the key to understanding this important insect order. Nothing will ever teach you as much as you can learn from your own observations, those things you notice while out on a stream or lake, with your waders wet in water, confronted by selective trout feedings on mayflies.
Dave has been studying mayfly hatches, photographing them, tying flies to match them, and honing presentation techniques to fish those flies for more that 30 years. Now you can benefit from Daves vast on-stream knowledge
