Green hats and shirts, shamrocks galore and cold pints of beer are customary for a St. Patrick’s Day celebration. This age-old holiday brings people of Irish heritage and other cultures together to enjoy a full day of fun festivities. Traditional step dancing, bagpipe performances and corned beef, cabbage and potatoes highlight the March celebration, but you absolutely can’t miss the parade. Each city might have its own way of commemorating St. Patrick’s Day, but these ones throw the biggest parties. (Diamond Bridges, The Active Times)
