Re: old guy problem - seeing #20 midge dries
I use parachutes with a white post. Generally, I know about where my fly is going to land and even better, about when it will land on the water. Both of these help to get me looking in the right place at the right time. Sometimes I see it, sometimes not. The right lighting helps a lot also.
When I can't see it, I just follow something floating where I think my fly is and keep my eyes focused on the general area, not a particular spot. I set on any rise in the area. Sometimes I am right, sometimes wrong!
P.S. I am 69 and getting old doesn't suck! I can go fishing any time I want and can pick the best weather conditions and never have to fish on WEEKENDS!!!
