The most Irish-American city in the United States is one of the best places to be for St. Patrick's Day. Not only is there a massive parade across South Boston, but there are also plenty of ways to connect to your Irish heritage with Gaelic food at every corner, a ton of local Irish pubs, ongoing bar crawls, and lots of traditional Irish music. Oh, and the city's own Dropkick Murphys usually plays at home on St. Patrick's Day.
