There's not 13 zones though. There's only 5 zones. Ashington, Blyth, Morpeth, Tyne and Wear and Tyne Valley. For some reason they've decided to print all the zone combinations out separately on there for some reason but I'm assuming it's just because it's what people are used to and it's easy for people to read it.

If it was promoting the tickets I'd agree though. But usually they use 1 zone, 2 zones and all zone tickets as seen when they first launched it here - https://www.flickr.com/photos/islandyorkie/5124828158/

Must admit it would be nice for a map of the actual zones on the internet somewhere though which doesn't seem to exist anymore since the god awful new website.

Edit: there is one but it's hard to find - https://cdn1-originals.webdamdb.com/1395...IOLRFF2RHA which is ironically wrong as you can get Morpeth + T&W tickets.
