Overview: On the loose in France's countryside, we drive up Alsace's Route du Vin for miles of vineyards, half-timbered villages, and feudal fortresses. We head to Verdun to walk the trenches of World War I before visiting Reims Cathedral to marvel at Gothic splendor and Chagall's stained glass. Our final stop is Epernay, the bubbly birthplace of champagne.
