Hello,
We've got some stuff for you to do here in New York City, and I'm thinking of Manhattan. All along the Hudson River Park you'll find lots of outdoor activities to do: bicycling, kayaking, skating, tennis, basket, rock climbing, golf and more.
Chelsea Piers is the preeminent venue for all this, check them out at

If you ride a bike, wear a helmet.
Cheers-
