We all knew this was going to happen eventually. If we're honest, we probably all thought it would have happened even sooner than this, but we managed to restrain ourselves until episode 3.
Anyway: this week's podcast is all about maps.
On it, you can hear from Stewart Mader, the founder of the Subway NYNJ campaign to add New Jersey to the subway map, who argues that improved mapping can be a cheap way to improve a transport network. You can read more on his campaign is here.
We also talk to Tim Fendley, the executive director of Applied Wayfind – the firm behind the Legible London signage – about how you go about mapping a city from scratch. Our interview with him is here.
All that, and Barbara and I discuss how maps can affect our perceptions of a city, and why it is that, er, I like maps more than than she does.
(We haven't bothered with a map of the week because it would have felt like over kill and/or choosing between your children.)
