An unusual stroller crosses Triangle Park. It’s black all over, a sleek racing pod with big, spoked wheels at the back. Struts of metal tubing protect the seat, and micro-mesh encloses it. There’s a brand name, too, normally seen on top of cars racing to catch Australia’s two-minute ski season.

I saw something like this in Mosman once, but it was red and contained a pair of angry Dachshunds.
