Dry fly fishing might be a possibility on the nicest, sunniest days, with a few midges or tiny olives and scattered caddis. Just put on a size 14-18 dry fly and fish. Water is cold now so any surface action is going to be very spotty. Nymphs fished at a distance are the best bet.
Winter, or at least a good taste of it, has arrived with record low temperatures and plenty of wind. Weather Guy says it may moderate a little bit near and over the weekend but it doesn't really look good to get out until next week. Trout are in the middle of their spawning activity which doesn't mean they are all "doing it" at any given time. If the weather improves a bit and water temperatures rise, fish could be taken on nymphs as per the "Tips" and "Techniques" section. The best bet for the weekend is the International Fly Tying Symposium in Somerset, NJ (www.internationalflytying symposium.com).
The Little Run in Boiling Springs is holding a fair number of fish if you can get by the poachers. Call (717) 486-7087 to report violators. Of course, office hours are 8 a.m. to 4 p.m. Monday through Friday so hopefully the poachers only poach during those hours!
