Tucked in behind the suburb of Yarralumla, on the western side of Lake Burley Griffin is Weston Park. While cruising around its expansive and beautifully mellow surrounds at twilight I came across a group of black swans. Worried they would scuttle off as I approached them, I was surprised to find them curious and gregarious. And though not diabolical or history changing in any way, my discovery of them did fit the first criteria of Black Swan Theory, which is that an event is a surprise.
