Rather than hijack someone's thread, I thought I would mention this in a different thread.

My understanding, from literature, is that the Kolzer a Firefly series of flies originated in Montana.

I have no personal knowledge so as to verify one way or the other. It is my understanding that a series were tied with differing body colors.

I always find the history of flies, and their origins, to be quite interesting.

For what it might be worth........
