It is strange how this time of year on the South Platte it seems flies that are not exact imitations of the hatching bugs work better. As many fly fishers know, these fish are fished over and over and have been fooled by the best. So, the best approach is to sometimes throw something different at them. And at least sometimes, this works. I do try to stay in "The ballpark" in terms of size and color. But over all when I look at what flies are hooked in the fishes mouth, I have to admit that the flies do not look like the tricos that are hatching all over the river. It helps sometimes to not be so logical, scientific and exact.
