Now you can understand 'leatherly wings" a little better.
Running around the Schoenberg Zoo (which is actually a really nice one, considering it is tucked back behind the Palace), we came across a really cool indoor Tropical rainforest exhibit. Really well done, and it was all pretty open.
Out on the ceiling, not too far away, we could see bats - big bats - hanging from the ceiling. They were actually kind of cute from far away.
