Out of curiosity, I went and looked at the timetable on the bus stop which is right outside work. And what Adelaide Metro in their wisdom have done is to display the full timetable for the entire 210-218 series of routes on the one sign, without a map to tell anyone which route actually goes where......maybe they assume that the general public doesn't read maps?
(Actually, this might explain why I have occasionally been asked by confused Flinders Uni students, which bus to catch!)
