We will be going to Chattanooga in a few weeks and I'm wondering about US 64 from nearby Cleveland to Blue Ridge, GA. Not as worried about the uphill climb but if our itinerary gets reversed and I have to drive from Blue Ridge to Chattanooga...how steep are the grades? I don't have any aux. braking...just the air drums. On coming home to FL from Blue Ridge, I don't think the stretch heading south out of Blue Ridge toward Atlanta is any concern.
I've ridden it on a motorcycle just before the Atlanta olympics. Many very tight turns, if I recall, but there were trucks traveling it, so I would think you could too.
