That’s what Matt Mayer, the guy behind the ExploreShanghai metro map is trying to do right now. He laid out his plan, and the rules, here, a blog post that finished with: “147 stations, eight lines, one manic Monday. Wish me luck!” You can follow Matt’s progress live on Twitter. His last message: “50 shanghai metro stations completed in 3h 7m 33s. Station 50 is west nanjing road. Shame i dont have time to visit marks and spencers :)” You can get in touch with Matt throughout the day. We’re sure he’d love to here from you — it’s going to be a long, boring Monday.
