We also went to ground zero and saw Freedom Tower and the amazing 9/11 Memorial.. The pools that occupy the footprint of the towers gave me chills. Given what happened in Boston earlier in the week, it gave us a even greater appreciation of this site... It is such a beautiful honor to all of those who passed away and a great demonstration of having the strength to rebuild after such a terrible tragedy.
We also walked to Battery Park and all along the waterfront.
