Longest and Shortest St. Patrick’s Day Parades are Part of U.S. History
Here's another piece of trivia about St. Patrick's Day that you may not know. The United States, specifically Boston, began the tradition of holding a St. Patrick's Day parade before the U.S. Constitution was even thought about. The first public celebration was held back in 1737! So you would think, naturally, that the longest parade on record would be in Boston, but it's not.
