Although I don't think it was tarmaced when the Incas were around. But I don't know. Maybe Blind Jack Of Knaresborough did it for them. I think he made roads. Possibly cambered ones. Is that the right word? Or am I thinking of Southeast London wells? And was Blind Jack a road maker, or did he sing the blues, blowing sad tunes on his harp, whilst complaining that his woman done left him? Or, to further complicate matters, was he somehow connected to Eleanor Of Aquitaine? The fact that they both shared the name "Of" indicates they were probably related...
