what part of the sprawling metropolis are you in?

http://www.bujinkannyc.org is in brooklyn, and while they aren't sword specific, they cover sword and will give you a solid base to learn many other sword styles from. ignore the silly name.

if it's not close, let me know, I'll see if i can find something closer, I don't know a lot of them though, i tend to only go up there to teach.
