We appreciate the support of our many seniors, and offer here the best value to help you come to the Zoo with your grandkids for a great day. Our Golden Opportunity Membership is only $30.00 annually and offers 7 visits within the year for grandparents and their grandchildren (must be under age 16) with your Zoological Society Membership Card. This is in addition to your subscription to ZoonooZ and the Humane News! Come visit and have a wonderful day with the grandkids without worrying about spending a fortune.
