text: Edinburgh speed limit changes - quick check of zone edge required here: 
  Full zone 1 speed limit boundary survey carried out today, and speed limits changed, but I forgot to check this small network of streets (Elder Street, St James Place). York Place is still 30mph. Leith Street here is 20mph. Where is the zone edge - at the entry to Elder Street from York Place or at the exit of St James Place onto Leith Street?
