A thousand rugby players invade New York for the Four Leaf Rugby Tournament on Saturday on Randall's Island. Fifty rugby teams from around the country will compete from 8AM to 7PM while spectators eat free food and drink free beer. A free "Try Rugby" clinic will be offered for kids under 14. After the last game, you can join the 1,000+-participant rugby pub crawl through the East Village and Lower East Side.
