We walked to the Arc de Triomphe both days we were in Paris. On both occasions we hopped onto the Metro, the first day to head for Notre Dame and the scond day to head for Gare du Nord and our Eurostar train to London. After two weeks of walking around European cities, we were getting a pity weary. You can almost hear the clatter of bike wheels that roll over the cobblestone on de Champs Elysees on the final day of the Tour de France each year (except his year), except for the noise of all the cars and police sirens that constantly blare all over Paris.
