Jim,
Please excuse the thread hijack. If your trip is still dual purpose w/ regard to fly fishing; may I suggest the head of the South Br. of Potomac at the Big Bend National Recreation area (paved) between Petersburg and Seneca Rocks on 220S. Also Seneca Creek (gravel but short hike to good fishing) off of 28 south of Seneca Rocks. Great small mouth float fishing (fly or otherwise) through "the trough" on South Branch near Moorefield. WV used to offer a very reasonable non-resident 3 day fishing license and likely still do. Just Google WVDNR and can purchase online and print your own, or you can purchase locally once you check it out. A word of caution though, once you fish it the trout won't be the only ones hooked!!!! Enjoy,
Jim
