Visit every Shanghai subway station in one day?

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.
