INT league has standardized rules and well described divisions. Our family has been involved for three years and we find these comps. to be a ton of fun.

In Nor Cal, the WWA grassroots league has basically the same divisions. The scoring is done differently, and we have found these events to be a great time also. Great people involved in both.
