There's two things I don't like about the roads on the Yorke Peninsula. One is that they're very bumpy, and two is that there's too much roadworks.
One good thing about these roads is that they took Vanessa and I to Marion Bay for a weekend of walks, beaches and a combination megacouch.
It was a nice trip. Not only do they have spectacular cliffs and places to swim, but there's also 4G mobile reception.
