As our city searches for power, ways of rebuilding, and outlets of assistance, New Yorkers are stepping up to the plate by serving food, providing shelter, and distributing resources (we've put together some ways to pitch in here). This weekend, if you're looking for a way to help, join the gang down at the Williamsburg Church — they're sharing their own personal life source (that would be blood) at the New York Blood Center drive. Due to hurricane Sandy, many blood drives across the city have been cancelled in the last week and the blood supply is reaching a critical low. Luckily, it takes only an hour to donate — an hour when you can also, you know, charge your phone, refuel on some snacks, and give back. According to the organizers, just 60 minutes could save three lives. Sounds like your most productive Saturday yet.
