My daughter and her family recently moved to Signal Mountain, Tn located near Chattanooga. My wife and I spent New Year's with them. There is one road going up Signal Mountain known as the "W" road. It has four hairpin turns which are a real challenge. We were in the cage, but I would never attempt this road on a bike. I've riden Deal's Gap with no problem, but the "W" road has steep grades and oncoming traffic cannot be seen coming up. If you entered one of these sharp turns while meeting another vehicle it would all be over. Just wondered if anyone else on the board had ever traveled this road on a bike.
