Went out white bass fishing this morning... the stream was absolutely full of fish. I bet a foul-hooked 8 or 10 of them...

But... I couldn't get a fish to actually take a fly for anything. I tried big flies and little flies. I tried black, white and everything in between. I tried fast. I tried slow. I tried deep. I tried on top. I tried in the middle. I tried upstream. I tried downstream. I could even put a fly right in front of a fish's nose, and he would just ignore it.

It was frustrating to say the least...

So, any ideas?
