We were in the tasting room of G.H. Mumm’s Champagne Cellars in Reims, located in northern France, sipping and comparing the lovely bubbly in our champagne flutes when our guide asked us if we knew about Route 66.  “Of course,” we said, “as a matter of fact we’ve driven the route.”  His smiled broadened as he told us that Route 66 is very popular in Europe and many aspire to travel to the U.S. just so they can make the drive.  Who knew?
