Dont worry Rex there are a thousand spot x's up north. They all have their day. The clue was the sand which is found on the eastern side of the skinny bit and mainly near the top. The fact that it was a trevally could indicate that it is inside a harbour like Parengarenga. Worth a look at any time. I just dug up some super 8 movies from the 1970s and early 80s fishing for kingfish in the far north. Awesome, we did very well with what we had then. In fact getting up there was a feat in itself.
