That is great to hear and it is so good that you are doing this with your children as well.
Our daughter went through private training for her Tong So Do black belt. She trained 1 hour one on one with her guru and then one hour in the group which consisted of families, people of all ages and races. It was a small private school and like you... a good environment to learn and be with people from all walks of life!
It is positive news to hear that some schools still do this!
