Living in NYC for pretty much my whole life, I've obviously been to every borough and pretty much every part of the city.   However, I didn't realize  until recently that I've never been to Governors Island.  It's just a $2 ferry ride from downtown Manhattan and it only takes about 3 minutes each way.  This little place is well worth the visit.  You get a nice view of the Manhattan skyline and you're pretty close to the Statue Of Liberty...
