I just came back from Colorado. I worked mon.-Sat. Went fishing on Sunday. I fished the Frying Pan, the Eagle river and the Yampa River below Stage Coach. The Frying Pan use Candy Cane's, Bwo emegers, EHC, and Baetis nymphs, #18-22. The Yampa river was the best fishing of the 3 I mentioned. Use Tricos, EHC, RS2, Baetis nymphs, Loop Wing Emergers. Hope this helps
