As we know, on Saturday, millions of people around the world will celebrate Saint Patrick's Day, which honors Patron Saint (or main religious figure) of Ireland. Communities across the United States will host parades, parties, and other festivities to mark the occasion. This year, cities like Boston, New York, and Chicago have organized massive events celebrating Saint Patrick's Day. In New York City, hundreds of thousands of people will gather to watch the Saint Patrick's Day parade--the nation's largest. It is one of the most watched parades in the world. Last year, almost 2 million spectators and more than 150,000 participants filled the streets. The parade, first held in 1776, is also one of the oldest. Chicago also throws a big celebration. Every year, the Chicago River, which crosses the city, glows green as event organizers dump about 40 pounds of fluorescence, a powerful dye, into the water. Boston keeps its parade rolling for three hours or more. It is the nation's second-largest parade. The city will also salute one of its most famous former residents, President John F. Kennedy, by opening the exhibit "A Journey Home: John F. Kennedy and Ireland," at his official library.
