I agree, moving from one city to another is quite complicated but moving from Boston to New York sounds like quite a journey, besides that the piano thing definitely makes the situation much more complicated, but don’t worry, there are moving companies They are long distance and they also provide you with a special service to bring pianos. In fact, reading the comments, I saw that Kenneth Cooper had just recommended an excellent company that provides you with this type of service. You should take a look at it.
