Had a girls weekend in NYC this spring. Its not my first visit to NYC but we sure hit all the tourist spots and got a great workout in the process, it was a busy 2.5 days with lots of walking. We even squeezed in a Broadway show...lots of fun that must be repeated!
Empire State Building, Statue of Liberty.
The new World Trade Center buildings (love the reflection!), the Washington Arch (reminds me of the Arc de Triomphe).
The Flat Iron building, Times Square at Night.
Rockerfeller Center and Radio City Music Hall both at night.
Manhattan Skyline as seen from Staten Island ferry (I truly miss the WTC towers in the skyline), and the Brooklyn Bridge.
