From the Youtube post:
750,000 participants from 72 countries convened in Denver in the summer of 1993 for World Youth Day and a visit from the Pope. Organizers feared the gang disturbances of the notorious “Summer of Violence” would scare away visitors, and yet for those 5 and half days, all violence ceased. This episode of Colorado Experience examines the largest gathering in Colorado history. Archival photographs, footage and modern-day interviews track the historic visit of Pope John Paul II, the Catholic Church’s revered leader.
