Which Flies are the right Flies?

You can choose the correct flies for each fishing situation if you have previous experience there or you can ask a friend who knows the water. My guide, Ray Hurley, and I walked up the bank to fish the tail of a pool on the Yellowstone River while my wife fished the riffle below. “What flies did you give your wife to fish”? inquired Ray. I told him the twelve flies I gave her. “Right on” said Ray, “she is better equipped than 90% of the anglers in the Yellowstone River.”
