Wouldn't be a good idea regarding the health and safety inspectors in Western Europe and North America although I like the effectiveness and low budget solution of it, but also surprised that it is so easily accessible for visitors.
Yeah, it's very odd that I could have easily strolled across the bridge and into the exhibit with Gaur and Banteng. There's no barriers to stop anyone from doing that, other than the fear of tumbling into a monitor lizard-filled moat.
