No-one's biting yet. I'm not sure how many of those are rideable (poor condition, or dead-ends that would mean descending >30% grade?). Ripley sounds pretty awful from the description. I have to say that I find it amusing to read this given that it's being described from the point of view of someone trying to drive a car up these streets!
