The Natural Bridge Zoo? I am glad to hear that. I can't believe they still have that lone elephant, though. I know you've said they don't have bears anymore and that was by far one of the worst exhibits. It sounds like they've maybe eased off on the promoting cub petting, which is good, because they were letting people get photos with tigers that were big enough to do some real harm.
I will say for anyone who visited the Catoctin Zoo recently-- I think I've seen you've posted photos from there-- those larger exhibits with the glass window weren't there during my visits as a child, and neither was the safari area. They had several concrete floored cages with thick metal bars (the worst one was the grizzly bear, who has since passed away-- it sounds like they still have the sun bear cage, but it seems to have more natural substrate and enrichment in it now), and large predators like lions, tigers, mountain lions, and wolves in flimsily fenced in areas. I wasn't shocked to hear that the wolves somehow got under the fence and dragged a mountain lion into their enclosure and killed it, or that the jaguars mauled a keeper.
The keepers always did seem to care about the animals, though, and the grounds were nice with lots of shade, and the place felt way less grim and disturbing than the Natural Bridge Zoo. It just had a weird haphazard vibe to it.
