This is New York City, and it's springtime. The combination begets baseball. Depending on your travel date, take a trip out to the Bronx, to New Yankee Stadium. Spring brings out model sailboaters too. Their craft are out and about in Conservatory Waters in Central Park. Not far away is the Guggenheim Museum. Something more avant garde? There's MOMA. Reserve tickets for a Broadway show and suspend disbelief for a few precious hours. Visit Lady Liberty and Ellis Island. Pay one last pilgrimage, to Ground Zero. Watch as new buildings soar close to where the twin towers once stood.
