I think most of us end up paying a small fortune to indulge in our Aiki hobby. All my salary in the 1980s went into training. When I think about it now, I must have been mad. In the 1990s I took control - teaching=minimal fees, no more gradings=cheap, BUT IT STILL COST A SMALL FORTUNE. Now, wandering.
Anyway, I'd like to join your dojo ... or one like it
