I'm down on the coast with the family now, not far from there. It certainly is brilliant cycling country, the roads up along the Woolamai Ridge in particular are amazingly traffic-free and have outstanding coastal views.
Very true but I like to have a flashing AYup front light and two rear flashing lights on all day just to make me more visible. And a rear view mirror in the country is not a bad idea. A bit daggy at first but you soon realise how valuable it is.
