Back in the 80's, I remember going to Lion Country Safari in Irvine, California. It was a drive-thru thing and very interesting, but is was a requirement to keep windows rolled up.
It's been a couple of years since we went to a zoo and the last one was here in Jacksonville, FL. The company my wife worked for at the time, helped sponsor a tiger area. However, compared to the Denver, CO zoo, the one here is much, much smaller. Jacksonville one has alligators (which, being this is Florida, would be expected), whereas the Denver one has buffalo and a couple of brown bears. Actually, the brown bears were cubs, when first moved to south of Denver and with each visit, within 5 1/2 years, we watched them grow up. Denver Zoo also had two free days during the winter months and we'd go then also. Don't know how it managed to happen, but none of those "Free Days" was there any snow.
Sort of wonder which animals could be in a Florida zoo and which not, since Florida can get so humid?
It's actually better to visit a zoo in the Fall, Spring or Winter time, since most animals find shade, and aren't that active, during the summer heat.
Wife and I really love going to the zoo, but the Jacksonville Zoo sure isn't as good as the Denver, CO Zoo.
