lot of dinosaur names as well are just being factual about size, like ‘mega’ - and actually a lot of the names are being factual about other things, like triceratops and pentaceratops: that's descriptive. Three horns; five horns.

HANNAH McGREGOR: Five horns. We're always telling you about the number of horns. And then a lot of them are just like, “We found this in this place.”

HZ: Yeah. The albertosaurus -

HANNAH McGREGOR: Albertosaurus!

HZ: - in Alberta. And, mastodon is meant nipple tooth, or nipple teeth.

HANNAH McGREGOR: …Sorry?

HZ: You look a little perturbed,

HANNAH McGREGOR: Perturbed and delighted. Vagina dentata is a sort of recurring theme -

HZ: It's a passion of yours.

HANNAH McGREGOR: It’s a passion of mine! Ha ha ha. Yeah, yeah, you know what? You're not wrong. It's a recurring theme in the book and my life. and so I'm really, I am intrigued by the idea of adding nipple teeth into the equation.

HZ: What is a park?

JUSTIN McELROY: I think ultimately a park is… and it's funny because people sometimes debate: should there be grass, should there be trees? Should there be a playground? Does it need to be a certain size? A park can be anything, that's part of the wonderful flexibility of how we use public spaces. I think, fundamentally, so long as it's a public space that people can hang out in and do a variety of activities, then you got yourself a park.

HZ: Even if those activities aren't hunting? You'll accept?

JUSTIN McELROY: I'll accept, because we're no longer in 17th century Britain. But I traveled the world for the last year before coming back to Vancouver. And every country, every city has different things that they think is an ideal park, and you can see that shape the set-up. But that ability to be different things, I think, is the shining example for what makes them universal.

HZ: Vancouver is a bit imbalanced because it has a lot of little parks and then one massive park at Stanley Park.

JUSTIN McELROY: And Stanley Park is the best park in the city. It might be the best urban park in the world, when you consider just how big it is, the range of things you can do.

HZ: Yeah, they filmed Twilight there.

JUSTIN McELROY: Ha! The amazing views that you have of the mountains and the ocean and the city, that you can jog, that you can bike, that you can walk, that you can see all different sorts of gardens and playgrounds: it's absolutely phenomenal, and an absolute jewel. And it's fun to contrast that with the other 242 parks. They can't all be winners, but they're all doing something.
