Least favorite place I have ever lived
Rude people - especially when driving, crowded, very expensive housing, apartment manager that wanted a bribe of 1 month's rent for renting you an apartment, movers that extort for a "tip", stolen hubcaps, etc.
Because of my career and having been a military officer, I have lived in 8 different places around the country. New York is my least favorite. I lived on the upper west side of Manhattan for 2 years (while in business school) and in Westchester County for 3 years.
NYC is great though in that there is so much there. Not worth it though vs. the negatives.
