Millions of people attended the victory parade for the Philadelphia Eagles on Thursday. Every one of them withstood sub-freezing temperatures, wind chills, and congested trains just for a chance to catch a glimpse of their athletic heroes. We went out to take their portraits, listen to their stories, and learn why Philadelphia is known for having "the greatest fans in the world."
