Mermaids in Wick

A LONG drive from Edinburgh to Wick, but spectacular scenery - light blue cloudless sky, green fields, yellow gorse, deep blue sea, snow-capped mountains in places, etc.

I'm staying near Wick harbour, and found beautiful gates there, one bearing this mermaid. There's supposed to be a geocache here, but I can't find something about 15mm long which is probably somewhere on the back of the gate in the semi darkness. Failed to find another cache, but finally found a different harbour one, I was keen to get one here to extend my "farthest north" statistic.

Lairg and Dingwall tomorrow, but snow is forecast so hoping for safe travels.
