Halloween on Franklin Street: Halloween on Franklin Street is a yearly tradition in Chapel Hill, North Carolina, that encompasses a massive gathering on Franklin Street, the cultural hub of the town.  The Halloween celebration began in the early 1980s as a considerably smaller event, involving Chapel Hill residents and college students from The University of North Carolina.  Attendees of the event dress up in creative Halloween costumes and walk up and down Franklin Street celebrating the holiday.  Since its beginnings, the event had grown in size every year until 2008.  Although not sponsored by the Town of Chapel Hill, the celebration has become an attraction for visitors from across the South.  Between 2004 and 2007, it was estimated that about 80,000 people converged on Franklin Street for the event, while Chapel Hill is estimated to have a population of 54,492 as listed in the 2007 census, evidence of the number of people who make the trip to Chapel Hill to attend.  Because of the size of the celebration, the Town of Chapel Hill closes Franklin Street to all vehicular traffic and prohibits parking anywhere near downtown.  Along with the big crowds come safety issues, with some of the biggest concerns being alcohol poisoning and gang-related violence.  To deal with these issues, hundreds of police officers patrol the downtown area throughout the entire night.  In 2007, approximately 400 police officers were deployed to Franklin Street to ensure that nothing got out of hand.  In 2008, the Town of Chapel Hill implemented new measures to attempt to cut down on the size of the Halloween celebration in an action dubbed "Homegrown Halloween" to reduce the crowd size and discourage people from out of town to come to Chapel Hill.  The shuttle service that had formerly transported people from park and ride lots to Franklin Street was shut down and the results of Chapel Hill's efforts showed when about 35,000 people showed up for the event.
