Fun things to do in NYC in the spring?

Every season in NYC is fun... although I do NOT live there---I am only 3 hours away by car and in fact was there LAST NIGHT (Monday)... my FAVORITE thing to do in the spring is to go to a NY Yankee baseball game at Yankee Stadium (from April - sometims November if they get in the World Series)... another thing is Central Park... (boating, horseback riding, biking, fishing, it has almost everything),... also Broadway shows, the Metropolitian Museum, the Googenheim Museum, the Bronx Zoo, Basket Ball (until the end of March) at Madison Square Garden, Hayden Planitarium, A visit to the Statue of Liberty and Ellis Island, or the view from the observation deck of the Empire State Building.. or maybe a HELICOPTER ride at night over the entire city --or during the day as well... or a boat ride up the Hudson River, Most of these attractions are open YEAR ROUND...
