Well, you could take our word for it -- a bunch of us have actually driven this route many times over the years -- whereas a complex series of algorithms predicts that it could driven in less time. But I have never seen "Mapquest" behind the wheel -- as far as the editing goes -- it was my mistake -- cleaning up navigation on the thread and I must have missed your posts. My apologies. Our advice is based on real-world travel conditions -- something that even the best math models in the world can only guess at.
