We recently had a visitor from California. She was in Sydney only for a few days, but it seemed to me that her tour group managed to fit in quite a lot, doing things that I wouldn’t have thought of, like going to the Queen Victoria Building (it’s a great building, but it’s just a shopping arcade) and the koala park. I’ve never been to the koala park, but every time I drive by I glance up at the trees hoping to catch a glimpse of a koala or two. (No such luck, leading me to question the veracity of their existence.) When our visitor showed us some of her photos, it pleased me greatly to see that, rather than being predictable tourist pictures, they were of signage and words. She was particularly fascinated by the instructions posted on restroom doors, the likes of which I had never seen until yesterday when, myself playing tourist for the day, I visited Echo Point in the Blue Mountains.
