We bump along a while longer and come to an intersection which is another dot on the map called "Twelve Mile". It's just a sign post to Wellington and a couple of other places. Oh well that is two "towns" I can cross off my list.
A bit of googling when I got home revealed on page 10 that Yarrabin was once a small village with a shop, school, hall and church but there is nothing there now. I'm so glad I didn't look that up beforehand, we would have missed this delightful drive.
