Ninjutsu in North Carolina?

Does anyone know any Ninjutsu schools/dojos in North Carolina? Preferably in the charlotte area of North Carolina. I have already checked out some listings online but I am sure there are more schools that do not advertise on the web.|||The only one I can think of is the bullshitsu club.|||I am sure they are there but try to avid Bujinkan they are a mall school I do not like them .
