Thread revival...
Just got home from Canaan Valley Resort SP. The road is actually designated Route 48 and it is, in fact, basically empty. We were on it early on a Saturday afternoon and saw a fraction of the cars that one would expect. When we got on it at the current "end" of the road near WV 42, it was completely empty minus a few work vehicles. We stayed on it till it turned into 55 and followed it all the way to 81 even though that was essentially south of where we wanted to go. But now we know. Once completed, this will be a fast track to Canaan Valley and Blackwater Falls State Parks and I look forward to it. While I wouldn't much recommend it on the motorcycles, it was ideal for pulling the trailer. Good stuff.
