I used to live in NYC, here are a few that come to mind...

Art/museums... top notch collections

Restaurants... you can find any type of food here

Sports.. I used to go to the US Open tennis every year... then there is football, baseball, MLS soccer.. all of these are within 1 hour

Sit down at a restaurant table on a sidewalk and just people watch

Broadway shows

Concerts

Beaches are close by

Hunter mountain for skiing is not too far

3 airports that have flight going everywhere

Those are just a few........
