A new sign by the river stopped me on a walk last week. I had to read it several times, using various techniques such as cocked head and squinting alternate eyes, to try and make sense of it. The Whangarei District Council line at the top is pretty straightforward but it's all downhill from there.
Looks to me like the (possibly foreign) sign writer was unnecessarily stingy with punctuation. And the graphic seems an ill fit for the text: the picture suggests 'no dogs allowed' but words suggest- eventually, with persistance and imagination- that dogs are ok if under the control of a (fouling or otherwise) person.
