Every club is unique in its membership. I am sure that SKA ZNA is open to new members. As far as comparing ZNA and AKCA, I am of the belief that the two parent organizations compliment each other. ZNA NorCal is not affiliated with AKCA at this time. Not real sure if we ever will. But then many of its members belong to more than one club as I do, the other clubs are AKCA affilitated.
Having said the above, please by all means join our club. There is a membership application available on our web site
www.znanorcal.org.
Our group is focused on learning about koi. Each meeting, as a general rule, has a class, lecture, judging exercise, or etc. about koi. Being able to attend the monthly meetings is part of the benefit of the group. Lots to learn and many to learn it from.
