Somehow, without really meaning to, I've been to NY 3 times. When Aussies travel, we often make it a 5 or 6 week event, so we can make the most of the long haul flights we have take to get overseas. A couple of these holidays have included NYC.
We walked day after day around the city, took the subway, saw all the sights, the lower east side, Brooklyn, Central Park, museums etc.
Maybe its just me, but NYC didn't really do it for me and I still don't know why. I feel like maybe I missed something? Its not that I didnt enjoy it, I did, but not as much as I thought I would. Its got character- maybe it would be cool to live there, instead of seeing it through the eyes of a tourist.
