There is a Dojo just a mere 10-minute walk from my home. I hope to suppliment my current weekly training at my own club (which is a good 30-minute drive) with regular training at this nearby Dojo, but cannot simply because it is run by a non-affiliated club.
I am not concerned about rank, grading or differences in styles (willing to wear my white belt all over again), but I am still not welcomed.
Well, there's no Aikikai rule against training anywhere in particular, affiliated or not. If it's a non-Aikikai dojo that is causing the problem then it's really their problem isn't it?
