Weekend Picks — Uke Fest, Princely Polo, Banging Downtown, Fireworks, and More

Happy 100th Birthday, Queensboro Bridge. You may not be New York City's most glamorous and iconic bridge, but you get the job done. After 100 years of connecting Manhattan and Queens, you deserve a centennial celebration and a Grucci fireworks display (check back on Monday for photos).
