Have lived within 8 miles of the zoo for 13 years and went today for the first time (shame on us). We took our 12 yr old granddaughter and we thoroughly enjoyed it. I was surprised, for a small town zoo, that it was larger than expected (30 acres, I think). There were few people there, which was nice, as you could see the animals much better. They have rinos, large apes, lions, tigers, and the herding animals of Africa, such as greater kudus, antelope, zebras, etc and many other animal species. Did not see any elephants, though. We found the zoo clean, and the animals looked well fed.
The ONLY things I saw that upset me was that many of the animals toward the back of the zoo had no water or water dishes and it was in the 90's. The small monkeys were isolated, in small cages, toward the back of the zoo, which I thought was sad, as they love to interact and watch people.
Overall, we thought the zoo was great and we will go back many times. For the people who think the $15 admission is expensive - get over it - there are A LOT of animals here, that must be fed. (How about considering a donation!) There is plenty of shade to stroll through the area and lots of seating if you want to stop and rest. Our granddaughter liked it better than Animal Kingdom. Try this little zoo a for a leisurely day. Don't expect the San Diego Zoo and you will have an enjoyable day.
