Hey the new Harbourside bike and walking track link is open!
And someone has left a smiley there for us. It's orange and made with spray paint. (Well it was there when the cycleway was new, it has faded now, so the new hint is to find the stump where the painted smiley used to be.)
So find that smiley 
and then find this smiley
. And smile at all the people on SH88 who can see exactly what you are doing
