Continuing on, we discovered a gloriously long uninterrupted stretch of the mother road. The concrete sections resonated the classic sound of mother road we had come to love... pa-thung, pa-thung, pa-thung. Our handbook summed it up perfectly: though the interstate is only yards away, you get a true taste of what cross-country auto travel was like decades ago. Savor it, and remember it after you've returned home. Well said. We did. And we very much do.
