Hemingway made it famous. Thousands of others have written about it.    This tour takes us to the San Fermin Festival in Pamplona that runs July 7-14.    I consider this to be the most exciting festival in the world and I have seen most of the others including Carnival in Rio and Mardi Gras in New Orleans.  We will be staying in a castle.  For the intrepid I will take you on a run with the bulls.
