Cool pics...it is funny how sometimes the fish just won't look up, even when the temps are ideal and there are hatches going on. I noticed that last week; we fished Lynn Camp our last day, starting mid-morning...nothing, either on dries or nymphs. Then, around noon, it was like a switch was thrown, and the fish started to look up, even in the deep pools. We stayed with dries the rest of the day, and we did pretty well.
One other thing I observed...the brookies tend to look up more, at least it worked out that way for us. They were hitting dries, even in the snow.
