Glad to know you are interested as well. You don't have to sign up for membership to attend ZNA NorCal koi club meeting. Try to attend the meeting next Sat first to see whether it is good for you or not. Of course, I am sure joining ZNA club is a good thing for any koi hobbyist...And, if you want to join, yes, it is a membership fee that including the Japan Nichrin Magazine in English version...
Please bring any koi folks down there to attend the meeting as well....We have nothing but great positive feed back from our club membership...
Looking forward to seeing you folks....
