Of course everyone imagines themselves on the red carpet in May at the annual Cannes Festival, formerly called the International Film Festival. Any time of year, however, Cannes is a delight.  Even in mid-winter the sun just might be shining, and as long as it is not raining local residents, usually immaculately coiffed and groomed, will be walking their poodles or other miniatures along Boulevard, or Promenade, La Croisette.
