Floating from Catherine's Store to Glenwood Springs is a pretty standard operation. Chuck and duck some streamers and stoneflies and catch fish. Well, the water is considerably lower than seasonal average. Temps are up. And, as you can see, nary a cloud in the sky. My nymph rig was catching squat, except the bottom. But a well known angler slightly older than me had the solution. Using a Sage LL (Graphite III generation) 4 weight and throwing a #18 Stimulator. Of course, perfect casting helped.
