835 Appreciating Stonework; Italy's Dolomites; Rediscovering Route 66

A master stonemason considers the great sites of Europe and shares what these enduring structures can teach us about permanence, craft, and human ambition. Then an Italian tour guide sheds light on the Dolomites, the spectacular setting where Italian, German, and Ladin traditions meet. Plus, an aficionado of American road trips tells us about efforts to revitalize historic Route 66 as a national heritage trail.
