I heard and was told by American Pakistanis and @

Actually I, my parents and most of my siblings visited NYC 4 years ago and we visited most of the historical landmarks and Manhattan, Brooklyn, Queens and Staten Island. We missed The Bronx though.
I am more familiar with the West Coast as I have studied in California for 1 year.
