I just called the zoo to renew my membership, which expired but which I have had for years. I upgraded last time to Diamond Club which gets a guest in with me and free parking at Safari Park. That category is now discontinued and replaced by slightly higher priced Keepers Club, which I was willing to pay. However when I called to renew I was told you cannot buy a regular membership or a Keepers Club membership unless you live in Southern California. Say What??? They have just lost a longtime supporter due to a policy that as far as I can tell has no rational reason. Because of this I doubt I will ever visit either San Diego park again.
