The Skyline Drive has been closed in most areas due to ice/snow. You can always call 540-999-3500, option 1, option 1, for updates on the closures.
These streams are getting cool and there are some areas that have snow around the streams. Be careful walking/hiking as these can cause some slippery conditions.
A jigging fly action with a two nymph rig such as a Murray's Adams Nymphs size 12 and a Murray's Professor Nymph size 12 on a Murray's Trout Nymphing 9ft 5X Leader often brings solid strikes in the cold streams. The swimming action may give the trout the impression the nymphs are attempting to swim away.
