I fish the Norfork and the White, near Mt. Home, Arkansas. The Blue Ribbon fly shop was out of business when I was there in June and October, but Dally's on HWY 62 at Gassville is great and so is Two Rivers on HWY 5 in Norfork. Just returned from 2 weeks of good fishing on the Norfork and camping at the Quarry/Dam campground. You could also go to the Mountain Fork near Broken Bow, OK. I've not fished it, but friends have and they like it. You would likely freeze in Colorado in November. I was on the Conejose during most of August and a lot of the nights were in the 40s then.
