We hit up the Perth Zoo today, and I finally got around to getting the zoo membership passes. So now we can visit regularly without it costing an arm and a leg! We inadvertantly stayed there the whole day too. Maybe it was the cart. I've been avoiding going on the "adult and kids' prices" days because it's always packed out, on the other days it's fine and we can always get a cart. Then the kids can hitch rides whenever they're feeling a bit tired and we don't end up walking over half the zoo before they're complaining of being tired.
The zoo visit was a zoo visit, the kids loved every minute of it, and the mother in law and I were tired out pulling them around in a cart. One of the highlights of the trip was seeing a mutant hibiscus (I have no idea what it actually was, that's what it looked like to me) and a numbat which apparently didn't come out much. The numbat not only came out, it quite happily traipsed around the place completely not minding our presence.
