The weather in NYC varies quite a bit and sometimes we don’t even know from day to day what the weather will be like. Be prepared for the rain or cold.
Of course, comfortable walking shoes are a must. New Yorkers are some of the healthiest Americans as we are always walking! There are also many things to do when the weather isn’t as pleasant as you would like for walking.
There are many fabulous museums to visit. Last count lists about 100 museums, including a sex museum! You can also spend the day on the subway viewing public art at the different stations. You can get more information about art in the subway stations at http://www.nycsubway.org/perl/artwork
