The glowing line between Mon Rapatta and Riverdown is a political boundary and not a river. There might well be a road there as boundaries usually either follow a geographical feature like a river or mountains (or roads), but it is not a river. You can tell the rivers of the southern flatlands by their squigglyness, which is typical for rivers whose path is not being dictated by hills and mountains. When you see a glowing squiggly line, it is a river that is a political boundary as well. Anyway, sorry for the confusion. I think it would be good to add roads to Ron’s map. I don’t have the original Photoshop file, but I can certainly overlay them.
