Luna Park is one of those memories etched in my psyche. I have a sense of going there with my Dad when we lived in Sydney, and we left when I was about 3 so it is buried pretty deep.
If you haven't been there it is an old 1930s or 40s amusement park and the entry in is through his mouth. It was just down the road from my hotel, so I took a stroll down memory lane.
You can see why that memory stuck. This face is big and weird enough to burn a whole in any three year old's brain.
