Here's a traveller's tip!
If, while driving along the banks of a pretty harbour, you spy some sort of shell fish farming and you decide to pull over for a better view......do not pull into the little layby that the oyster farmers use to store their old nets. I think this was the briefest stop of our trip!! Old oyster shells and the hot sun are not a good mix.
I don't know anything about oyster farming so have no idea what the little floating shed is used for.
I liked the little general store perched above the rocks of the harbour.
