Secrets of New York

Hi,
i am going to NY next week and i am looking for some places, tourists normaly don´t see. I´ve been serveral times before in NY and this time it would be great to see somethin new. I bougt the book "Secret New York". The book ist from Protected content i think "even" in NY things changed a bit since.

Does anybody know a place where i can take part in an krav maga session.

I will be in NY from 03 april till 07th april.

I would be very thankful for some suggestions.

Best wishes
