Every one has a little Irish in them, and today Pershing Square was the place to show off your green. The Young Dubliners performed a free concent, which had everyone on their feet doing a jig, and the Pershing Square fountain became a magical Irish waterfall. Later, the horde headed around the corner to Casey's Irish pub for green beer and Guinness, where the party will no doubt continue late into the night. Happy St. Patrick's Day!
