I like and applaud this zoo (if not its use of drawing pins on laminated signs), but the language here is shocking: "painted dogs" is bad enough, but "reserve" really does have me coming over all Clinton Keeling. And that's not necessarily a good thing!
'Reserve' is a relic of the 'walking safari park' ethos they started with, and have sort-of carried on with. So while it's odd, it's at least explicable.
