St. Patrick’s Day Parade in NYC celebrates Irish and immigration

It was a sea of green along Fifth Avenue on Saturday as New Yorkers celebrated St. Patrick’s Day a day early.

Some 2 million spectators lined the streets to cheer on the bagpipers and dancers that have become as synonymous with the parade as wearing green.

The parade is typically held every year on March 17, unless it falls on a Sunday when it could conflict with religious observances.
