@Benosaurus Its been probably twenty years.... Not an awful lot of major changes during that time IMO, though there have definately been some improvements I think, particularly the indoor Orangutan area with the added equipment it has now is much improved, while the outsides are probably the best they can be now until they can build the planned new extra outdoor area. I was disappointed not to see either of the male Orangutans- even at midday neither were visible inside or out. I did like the Gelada enclosure though.
