I need to use a headlamp. Perhaps one or two of these fish would have hit the larger fly. At least I could have seen a parachute #10 on the surface, not by shining the headlamp on it, but with enough light left in the dusk.
Fly fishing can get complicated. I also need to bring along reading glasses to tie these flies on. It felt good walking out, as it had as I approached the spot where I caught the brown. Felt glad I caught one.
